AI-driven energy startup Octopus hits $2Bn mark after $200M investment from Tokyo Gas – TechCrunch

The deplatforming of a president – TechCrunch
Have you heard about Challenger Banks? Now meet challenging energy suppliers. To start the joint venture, the UK's Octopus Energy has received $ 2.06 billion (£ 1.5 billion) after an investment of $ 200 million (£ 150 million) from Tokyo Gas for $ 9.7 million. Octopus will own 30% of the venture, with Tokyo Gas owning a majority. Five years after operation, the octopus is now close to the valuation of British Gas owner Centric.
Octopus will now launch in Japan as a brand with its trademark 100% renewable electricity operations that use an innovative AI and data-based platform to balance the load around the grid. Its Kraken software has been licensed to access 17 million energy accounts worldwide, among others from Origin Energy, Enpower and E.ON, Good Energy and Hanva Corporation.
In a statement, Chief Executive Greg Jackson said, "This joint venture will bring our exciting approach to renewable energy and technology to the world's largest competitive energy market, and the investment will further our mission."
Australia's Origin Energy is also set to take a $ 50 million (£ 37 million) stake in Octopus after a major investment in April when Origin bought a 20% stake.
Octopus says it aims for 100 million customers worldwide by 2027, and has recently launched in the US, Australia, Germany and New Zealand.
In the UK, Octopus has a 5% share in the energy supply market and, according to the company, counts 1.8 million homes in its retail portfolio.
Tokyo Gas President Takashi Uchida said: "Through this partnership, we will contribute to the achievement of a better lifestyle for customers by value creation and consistent delivery to each one of them."
Japanese renewables lagged Britain by 50% (18.9% of renewable energy in Japan vs. 37.9% growth in Britain in 2019) so the potential for growth is significant. Japanese Prime Minister Yoshihida Suga aims to reach net-zero by 2050.
Octopus has also launched electric juicing network Electric Juice in the UK and partnered with Tesla to launch Tesla Power.

What a fascinating discovery for you… to know your father was filmed – with a ACP on his belt – at one of Hitler's living quarters. He was one of the most maniacal of them all. You must have felt a tremendous range of emotions burning that painting…one that your father sent back from the war.
You're right about the range of emotions before burning that painting. I had some friends who urged me to sell it, and I did call Christie's auction house to see what it might fetch. But the thought of getting money, no matter how indirectly, from something created by Adolph Hitler proved to be more than I could stomach. It just creeped me out and I reached for my cigarette lighter and a bottle of BBQ starter! I think I made the proper decision.
For those unfamiliar with firearms, the "ACP" Mustang.Koji refers to is the .45 Colt automatic pistol shown holstered on my dad's belt in the bunker photos. It was the official pistol of the U.S. military for many years, before and even after the second world war.
I had one a friend had carried in WWI and it was quite a solid piece of work. I sold it when we had kids; got rid of almost all my guns at that point.
Jim. Thanks for posting these photos. I knew and remember your dad.
As you know, your dad is a man I greatly respect and remember with affection.

Rush Limbaugh: GOP and Dems Both Fear Palin
Last night Rush Limbaugh went On The Record with Greta Van Susteren. Among the topics discussed were Governor Palin and the fear she instills in both the Democrat Party and GOP establishment. Via Hiram Reisner at Newsmax:
Talk Show Host Rush Limbaugh says if he were President Barack Obama he would not want to face a staunch conservative like former Alaska Gov. Sarah Palin because she carries a frightening message — that he is beatable. Limbaugh also said on Fox News Thursday night that the GOP establishment fears Palin as well.
Fox News' Greta van Susteren asked Limbaugh whether Palin's announced bus trip was the beginning of her presidential campaign.
"I think this bus trip — it's certainly designed to get people speculating that she's in," Limbaugh said. "The thing about Sarah Palin to me is that she has now learned to relish and to profit from all the attention — negative or positive — and she certainly knows negative attention.
"She has suffered slings and arrows — she's had the media …exam — unlike any other Republican candidate," he said. "And I think she has now come to grips with the fact that that's part and parcel of the process. And I think one of the things that she enjoys is just rubbing it right back in their face. She knows that they are trying to intimidate her into silence.
Limbaugh said Palin is mastering the things she will have to master if indeed she decides to run. He also said results of the most recent Gallup Poll that showed her only two points behind former Massachusetts Gov. Mitt Romney "shocked me" — especially since she still hasn't made a decision.
"That was startling," Limbaugh said. "Greta you've asked the question of the day — you've asked the question of the campaign: The Republican Party is really royal right now, 'Inside the Beltway' intelligentsia, power base is not oriented towards conservatism.
"Conservative Republicans make them nervous," he added. "'The Inside the Beltway' ruling class — the elite — they're more oriented toward candidates they can attach the word 'serious' to — which is another way of saying someone who is boring, who doesn't ruffle feathers, someone who exudes an air of formal education and sophistication — she doesn't exude that, and I think it's going to shake a lot of people up.
"You know the effect that she has on establishment Republican people," Limbaugh continued. "They're just as frightened in their own way as the Democrats are of Palin and one thing I think is inescapable — particularly in looking at the Democrats — the Democrats and the media will always tell you who they are afraid of by virtue of who they spend time trying to destroy."
More here. While we're on the topic of establishment Republicans, one of Mandate Mitt's gutless army of anonymous staffers launched another misogynist attack against Governor Palin yesterday, basically calling her an "entertainer". Not that misogynistic attacks from Mitt are anything new. Via Byron York:
"The bottom line is Sarah Palin is not going to run for president," says a Republican adviser close to front-runner Mitt Romney. "She's making money, she's moved on, she's kind of an entertainer rather than a politician. She still has some sway with the grass roots, but she is not going to run."
This is hilarious. "Some sway with the grass roots", eh, Mandate Mitt? Not going to run? And you know this how? One of T-Paw's boys joined in:
"I don't think she's going to run," says a Republican close to Tim Pawlenty. "She has faded a lot in the last few months.
Faded a lot in the last few months? Where he got that (yes, I'm assuming it's a "he") I have no idea. He likely pulled it from the data base in his lower intestine. There's certainly no empirical evidence to back it up. While polls this far out are essentially meaningless, I haven't seen any that indicate T-Paw surging ahead of the Governor. Quite the opposite. When you read such nonsense from these fools, you're left with the impression that they're chasing white rabbits in Alice's Wonderland. Either that or their benefactors are paying them quite well to be willfully ignorant. If these Republican insiders are so convinced the Governor isn't running, why all the sudden commotion yesterday?
That was fast.
Hours after Sarah Palin announced a "national tour" that will point her towards still to-be-announced destinations in New England, several other Republican presidential hopefuls revealed plans for making their intentions known:
Rep. Michele Bachmann, R-Minn., told Iowa reporters in an evening conference call that she'll be making an announcement, sometime next month, in Waterloo — the Iowa town where she was born;
Presumed Republican 2012 front runner Mitt Romney let it be known that his long-awaited official announcement will take place on June 2 in New Hampshire;
Former Sen. Rick Santorum has also set his announcement date for June 6.
Hmmmm. She makes a couple moves toward running for the nomination and they jump with more alacrity than cockroaches when a light comes on. Just a coincidence, I'm sure. York does flirt, momentarily, with lucidity in his piece:
Maybe these representatives of rival campaigns are just spinning.
Gee, Byron, ya think? Paging Captain Renault!
Rush is right: Establishment Republicans are just as afraid of Governor Palin as are the Democrats, and their spinning is becoming increasingly implausible. Denial.

Wenger questions Arsenal mentality after shock defeat
Date: 1st February 2017 at 9:00pm
Arsenal manager Arsene Wenger believes there was nothing wrong with the Gunners' preparation for the match against Watford yesterday.
A poor first half display meant that Arsenal went in 2-0 down at the break after goals from Younes Kaboul and Troy Deeney. When asked about the team's preparations after the match, Wenger instead asserted that subconsciously some players could have felt they just needed to turn up to win last night. He was quoted by Arsenal.com as saying:
"I have no basic regret, looking at the preparation, in the way that we prepared for the game. And did we think subconsciously that we will turn up and it will work? I don't know. But from the stands I agree with you that our first half was not at the level that we wanted."
The surprise home defeat means the Gunners slipped to third in the table, and are now nine points behind league leaders Chelsea, who drew 1-1 with Liverpool at Anfield yesterday.
Arsene Wenger's side will now face the Blues next up at Stamford Bridge on Saturday afternoon with the Gunners' title ambitions hanging by a thread. A win would bring Chelsea back within touching distance with 14 games to go, but a draw or defeat would probably spell the end for the club's chances of winning the league for another season.

This post I thought I'd give a virtual tour of Japanese shrines and temples. I also thought I'd mix both in a single post, since that's the way it is here in Japan. Sites can be both Shinto and Buddhist at once. I found that strange until realizing it mirrors Christianity's spread in the west, where often, it was just layered over the indigenous religion. Local gods were given the names of Catholic saints and locals continued to worship as they always had, half-converted until a few generations later the old religion was simply forgotten and swept under the floorboards. Buddhism did the same thing, except it claimed local deities were subservient to Buddha and even had them convert. Some Shinto gods even assumed roles as buddhas themselves. So let's start at the beginning, the shrine gate. The gate serves as the physical and spiritual entrance to the realm of the gods. In the past, the wilderness had been considered a mystical place, the place of the gods, and shrines had been built on the edge of the forest and mountains. When you step through the gate you are symbolically stepping into the deity's' place, which is why you are supposed to only enter through the gate. Following the gate there is often a long walkway or staircase, intended to guide visitors into a meditative state where they leave the world behind. This is more for temples than shrines, but as I said, sometimes it's not so easy to distinguish between them. Next is the cleansing fountain. It's traditional to cleanse you hands and lips before going to pray at a Shinto altar. On your way to the main altar you're likely to pass a garden. Many if not all of these are Zen-inspired. Tea ceremony master Rikkyu was once a Zen monk, and his extremely influential school of tea ceremony is based on its principles. It's said he once ordered his son to clean his garden in preparation for a tea ceremony party. After scrubbing the rocks and raking the leaves for hours and still not meeting his father's approval, he gave up in a huff. Rikkyu went out into the garden and shook the nearest tree, letting the leaves fall as they would. The garden was ready. Your likely to see a buddha statue or two, and many jizos. These are usually found in temples and not shrines, though I've seen them in some. Jizos protect travellers and children born and unborn. They are said to stand between spiritual and physical. The red bibs are given to them by people to gain merit for the afterlife. It's doing the jizo a favor. You'll also see them wearing caps and scarves knitted by old women. There is a folktale about an old man who gave reed hats to a group of jizos, and was then blessed by them with food and supplies. These buckets you will only find in temples. They are used to hold water to clean graves. Buddhism handles death in Japan, which is one reason it became so popular after it made its way from China. The dead being impure, Shinto tended to avoid contact with them, leaving Buddhist funeral rites to fill a large whole in Japan's dealing with death. Larger sites that you can enter might have an uguisubari. This is a hall made of squeaky wood that was used to detect ninjas and thieves. When stepped on, the wood makes a chirping sound like a bird. "Uguisu" is a Japanese bush warbler. And the altar. Most shrines will have it outside like this. Though larger shrines may have several deities enshrined–one main deity and many subservient ones. Temples will have a buddha statue, though they may look quite different than you expect. Like this picture. This is from a temple, not a shrine, and that fierce-looking guy is a warrior buddha. And that was the main aspects of temples and shrines in Japan. Hope you enjoyed the tour.
Utterly fascinating. It looks like a place I'd love to visit one day.
I just got back from Japan and visited a slew of shrines and temples. It seems, no matter how many I visit, the reaction is always the same… I am in awe of these sacred spaces.

If the carpet is not eliminated, additional water will remain beneath the carpet raising the prospect of there's secondary damage to your industrial or residential property. Also, leading to needing more time and desired equipment to completely dry the property.
When hardwood is going through the drying procedure, complete extraction of the water is essential only as each other surface. Hardwood emergency flood damage mats are utilized being put on the floor and attached to the vacuum cleaner. What is more, the time period required for a complete extraction is determined by the whole amount of water found on the ground.

Looking for an interstellar comet 2I/Borisov home system
Our computer codes and stellar data sets allowed us to search for a potential source of the interstellar comet 2I/Borisov among nearby stars. The double star Kruger 60 seemed to be the best candidate but radial velocity data were lacking. This possibility was ruled out by the new radial velocity of the Kruger 60 center of mas obtained form private communications. We will describe methods of such an investigation and the limitations in making results publicly available.

Pill aperture photometry of the near-Earth Asteroids
Near Earth Asteroid photometry is struggling with the problem of their observed high velocity in the sky during approaching Earth what causes image stretching of asteroid and/or stars on CCD frame (they leave trails). In such case typical differential photometry with circular apertures does not give good results. The solution is a pill aperture that perfectly reflects the shape of the trails. As a result, we save optimum signal-to-noise ratio. The shape of this aperture can be described as two half-circles connected by a rectangle. The use of the pill aperture is not limited to asteroid photometry. The problem of the observed high velocity in the sky also applies to artificial Earth satellites. Pill aperture can also eliminate the problem of star photometry during unexpected movement of the telescope e.g. during a
sudden gust of wind.

Eclipse de Sol Chile 2019
The "Eclipse de Sol Chile 2019" project was an expedition to Chile to observe the total solar eclipse. The expedition was attended by students and Ph.D. students from Adam Mickiewicz University in Poznań, University of the Arts Poznań and the Nicolaus Copernicus University in Toruń. The total solar eclipse could be observed in Chile on July 2, 2019. For observations, we chose the mountain on the Pacific coast in the region of La Higuera (29.4544° S, 71.2472° W, 795 m a.s.l.). At this location, the total solar eclipse lasted 2 minutes 35.8 seconds. The first contact of the Sun with the Moon occurred at 19:22: 53.6 UT. The beginning, maximum and end of the total eclipse phase were 20: 38: 24.0 UT, 20: 39: 42.1 UT and 20: 40: 59.8 UT respectively. The sun was then at an altitude of 13.6° and azimuth 306.8°. For registration we used: Canon 6D camera with a 100-400 mm telephoto lens (photographs), Canon 650D camera with a 150 mm lens (film), Nikon D90 camera with a 200 mm lens (photographs), Canon 700D camera with 800 mm lens (photographs). We recorded the Sun trajectory using a meteorological device called a heliograph.

Origin and evolution of long-period comets
Traditionally, long-period comets (LPC) are defined by their huge orbital periods: 200 yr at minimum, but many have effective orbital periods as long as millions of years. At the first sight, they are mysterious visitors to the inner Solar system on incomparably elongated orbits from its extreme outskirts. Yet, their population may be well understood using advances in our knowledge of the Solar system early evolution and a flood of new and accurate orbital data. I shall describe an evolutionary model for the LPCs that reasonably well matches their orbital architecture. Admittedly, it is less successful in describing their observed flux to the inner Solar system, though I shall discuss plausible reasons for this mismatch. The model allows to make predictions which could be tested by LSST observations within the next decade.

gaia@home
Project gaia@home (former GAVIP-GridComputing) is an ESA project run by Poznan Astronomical Observatory staff which will add additional features to the Gaia archive by incorporating CPU power of volunteers' computers of the BOINC grid (best known of its SETI@Home project).
gaia@home eventually will allow to define a series of jobs which will be able to read entire Gaia archive and compute some CPU intensive jobs on the BOINC platform (best known from SET@home project). The users, in order to use the GAVIP-GC software will provide source code to deal with their scientific problem. Everything else (e.g. reading data from Gaia, communicating with BOINC, downloading the results) will be done by gaia@home software.
During the seminar I will present the current status of the project.

Proper motion studies of methanol masers around high-mass protostars
High angular resolution studies of the 6.7 GHz methanol maser emission provide one of the best existing tools for deriving 3D kinematics around high-mass proto- or young stars. Regions that are hidden in the dense environments and are not easily reachable at other wavelength ranges. Particularly, multi-epoch, sensitive observations using the very long baseline interferometry networks are successfully used to investigate proper motions of single maser clouds in high-mass star forming regions.
I will present recent studies of sources that showed ring-like structures at the 6.7 GHz line and were discovered in the Torun survey with the 32-m radio telescope. Using the European VLBI Network over 10 years and obtaining images of emission with miliarcsecond angular resolution, we can follow detailed kinematics (tangential velocities of order a few km/s) of masing clouds in the vicinity (ca. 1000 au) from central stars. Unexpectedly, masers are expanding from the centres of the ring, indicating a physical relation to an outflow or an expanding bubble rather than a disc.

Optical interferometry of symbiotic stars
Optical interferometry is a method of astronomical observations that gathers light collected by several telescopes observing the same object simultaneously. It allows to measure sizes and even exact shapes of astronomical objects. We use optical interferometry to examine a large number of symbioticstars. Our observations and analysis will allow not only to determine the size of the stars, but thanks to reaching their innermost regions, we will be able to observe directly the extension of the red giant's surface due to tidal forces. I will present the first results of this project.

The nature of dark matter in the theory of light and matter
A new theory of light and matter incorporates a complex scalar field, responsible for the mutual confinement of light and rest mass in "elementary" particles. This field parallels many of the observed properties of dark matter and dark energy. These include the gravitational effects, the property of the observed increase in the rate of "expansion" of the universe, the transparency of the substance to light and the non-observation of dark matter to date. This invisibility does not mean that the substance is immune to experiment. Experimentally observable effects of this field in the nearby solar system, the local galactic cluster and the wider universe will be discussed. As well as the usual properties associated with dark matter/energy such as gravitational lensing, the observed expansion of the universe and galactic rotation, the talk will discuss, among other things, solar coronal heating, high energy particle generation (x and gamma rays and high-energy charged particles), and matter-antimatter asymmetry in the physical universe.
John Williamson worked at CERN for 7 years, in nano engineering in Philips for 5 years, and as an associate professor in the College of Science and Engineering in Glasgow University for 27 years. He is currently the director of Quicycle an international group devoted to the advancement of science. He has published widely in the fields of experimental physics, nano-engineering, and in theoretical physics. He has (co-) authored over a hundred papers. He has over twelve thousand citations in peer-reviewed papers and an h-index of 45.

Perturbers of cometary motion (case study)
Since 1950 when Oort published his paper on the origin of comets a continuous search for the stars which were able to perturb cometary motion has been conducted. The aim of this presentation is to discuss two cases in which the data obtained from observations were used and stellar perturbations (of different intensity) on cometary motion were detected. Our results show how different the dynamical evolution of comets would have looked when their motion was considered only in the Galactic gravitational potential. Uncertainties both in stellar and cometary data were carefully taken into account. Our analysis indicates that the occurrence of stellar perturbations on cometary motions is very rare and the uncertainties of these effects are hard to estimate.

Automatic differential photometry and photometric callibration of asteroids in CCD frames
At the beginning of XXI century astronomy entered the Big Data era, in which robotic telescopes produce petabytes of data. Most of them consist of CCD images which require automatic measurements by the specialized photometric pipelines. In our Institute we still use a traditional method of aperture photometry which requires frequent manual intervention. While beeing well tested, this approach starts showing its weekness when faced with the increasing inflow of observing data. It also lacks photometric callibration which recently became a routine procedure in differential photometry thanks to the sky surveys (SDSS, PanSTARSS) which released their high accuracy photometric measurements of millions of stars. In the talk I will present the use of the photometric pipeline of Michael Mommert for the automatic photometry of asteroids and briefly describe main stages of the computations The application of this procedure for derivation of asteroid phase curves will also be shown.

On the physical nature of 'Oumuamua and detection of asteroid trails
Discovered last year, the first recognized interstellar visitor in Solar System, 1I/2017 U1 (Oumuamua) is the long-sought link between our own Solar System and systems around other stars, heralding an onset of a new field in astronomy. Our group has played an important role in the effort of characterizing this unique body. We were awarded 12 hr of DDT on the Gemini North 8.1-m telescope. As a result, we obtained the highest quality photometric and spectroscopic data, which have revealed some remarkable and unexpected properties. I will review the current state of knowledge on Oumuamua, discuss the impact of this body on science and society, and speculate on possible future avenues.
In the second part of my talk, I will present our first dedicated search for dust trails of asteroids, that forms along the asteroids orbit as a result of their disruptions. The trail can be observed for many years, as showed by the studies of two recently disrupted asteroids, P/2010 A2 and P/2012 F5. We argue that a dedicated survey with a large telescope can possibly detect much fainter (thus older) trails – precious remnants from historical disruptions – thereby providing basis for detailed research into the causes of the disruption. A pilot survey was conducted by our team at SALT. We have successfully detected the known ultra-faint trail of the disrupted asteroid P/2012 F5 – proving the concept in terms of technical feasibility. I will present the main science goals of the survey, discuss the results from the pilot phase, and draw conclusions for the full phase which has been recently initiated.

NPDT: a web based service for determination of asteroid rotation periods from their lightcurves
Working under a contract to ESA we are preparing a web-based Service for Archival NEO Orbital and Rotational Data Analysis (SANORDA). It includes a NEO Period Determination Tool (NPDT) which takes asteroid lightcurves from a database and uses them to derive their rotation periods. The algorithm is based on a well known Fourier series analysis and implemented as a python program called PerFit. In the talk I will present a typical use cases of the NPDT service, which is currently in a beta stage. Using PerFit I will also show how the uncertainties in the asteroid lightcurves influence the accuracy with which their synodic periods can be derived.

Rotation periods of V-types asteroids outside the Vesta family
Basaltic V-type asteroids and their fragments are collisional remnants of planetesimals that existed 4 billion years ago. Their distribution, physical and dynamical properties provide important constrains on processes such as planetary differentiation, planet formation and evolution of planetary systems.
Asteroids with the prograde sense of rotation, located in the inner Main Belt, that have semi-major axes of their orbits smaller than that of Vesta, are less likely to have migrated from Vesta due to thermal forces dragging them outwards (the Yarkovsky effect).
Assuming that the inner Main Belt is populated only by the Vesta like objects, around 81% of asteroids in the so-called scattered resonances region are expected to have retrograde sense of rotation. Similarly 40% of objects in the low inclination region, should have retrograde rotation. Substantial surplus of asteroids that have prograde rotation could indicate that also other planetesimals (different from Vesta) contributed to this population. Those predictions are verifiable via photometric studies in which asteroid lightcurves are used to derive senses of rotation.

'Oumuamua - knowing much more we still know almost nothing
Almost 60 papers were published on the first macroscopic body coming from an interstellar space. Both ground-based and space-born most powerful telescopes observed it for many hours. Unfortunately such a short visit caused substantial lack of knowledge on its nature and as a result we have more questions than answers. It appeared even a suggestion that it is an alien spacecraft, rather ruled out by the majority of the astronomic community. Anyway, strange and mysterious name: 'Oumuamua fits very well in this case.

Ionization instability in low mass X-ray binaries
I want to present a study of disk instabilities in black hole binaries in which X-ray novae outbursts were observed. Soft X-ray transients (SXTs) are the subclass of accreting low-mass X-ray binaries (LMXB) and they spend most of their lifetime in quiescent state. Those objects an be discovered only during outburst phase when they become one of the brightest sources in the X-ray sky. Almost all of SXTs are recurrent sources. It was noticed that intervals between outbursts may vary from tens of days to decades or maybe even longer, as only a few systems have shown two or more outbursts. Usually we observe outbursts of the regular, symmetric shape or so called fast rise exponential decay (FRED) shape which is typical for X-ray novae outburst. I will present numerical simulations of instability process that occurs in X-ray novae sources. I've calculated models which predict time dependent evolution of ionization instability in an accretion disk around black hole, assuming viscosity parameter to be proportional to the total pressure. As a result of modelling I get confirmation that the ionization instability in the examined sources is responsible for occurrence of characteristic X-ray novae outbursts. This study shows how analysis depends on assumed global accretion disk parameters and chemical abundances.

LEO OBJECTS ORBIT DETERMINATION COMBINING LASER RANGING AND PASSIVE OPTICS MEASUREMENTS
Satellite catalog contains orbits of about 20000 objects. Maintenance of up-to-date catalog requires systematic observations of all objects. To obtain necesarry data a high precision measurements of satellite positioning and precise timing are required. An appropriate process of observation and reduction is required, as well as specialized software.
Although observations of satellite objects have been carried out for over 60 years, the use of telescopes in the case of cataloging objects moving below 2000 km above the Earth's surface is a novelty. The technological development that has taken place over the last decade allowed for high quality astrometric observations of satellites in LEO orbits (Low Earth Orbit).
Observations of LEO objects were performed using the RBT telescope over the past few years. We are able to analyse these observations and determine orbits. Currently we want to have possibility to use other type observations. In this talk I will present preliminary results of combining laser ranging and astrometric observations used in the orbit determination problem.

The discovery of a hot cocoon around an exploding supernova
I will present the results of observations (including those with RBT/PST2) of a gamma-ray burst (GRB) 171205A and the associated supernova (SN) 2017iuk, which led to the discovery of a hot gas cocoon. This was possible because observations started very early and the jet emission was weak. This gives support to the theoretical models of GRB/SN explosions, which predicted the existence of such a cocoon. This discovery opens the possibility to study internal processes during explosions of very massive stars, and hence will shed light on the understanding of the production of heavy elements. In case you miss this seminar, I will also give it at the Faculty of Physics on 3rd of April:

Population synthesis of classical novae population
Cataclysmic variables (CVs) are interacting binary stars that consists of a degenerate white dwarf accreting mass from a normal star donor. Our understanding of evolution of such systems have been challenged by properties of their known population, such as white dwarf mass distribution, orbital period distribution and their space density. With the recent developments of population synthesis codes we are able to reproduce the CV population characteristics. However, there are still unsolved problems posed by the population of classical novae among the CVs, such as for example why there is only one system known to have both dwarf nova and classical nova outbursts. In my talk I will discuss the recent developments of population synthesis codes as well as my work on understanding of classical novae population using population synthesis.

Modeling of symbiotic star SY Mus based on photometric and spectroscopic observations
Binary stars are very important topic of astrophysical research. Using the data from photometric and spectroscopic observations, we are able to determine much more physical parameters of the system's components than in the study of a single star. We obtain information not only about effective temperatures, metallicity, rotation velocity, but what is the most important, masses and radii of two components. Compact binaries become crucial when considering the evolution of stars and their influence on the later generations of astronomical objects. The system composed of a white dwarf and a red giant, is called symbiotic star. Researches on these types of objects contribute to a more accurate understanding of the geometry of binary stars and mechanisms in these systems. Our work is dedicated to modeling the physical parameters of the SY Muscae, symbiotic star in the southern sky. Based on photometric and spectroscopic observational data, in the infrared and visible range, using the PHOEBE program we created a model of light curves and radial velocity. This model clearly describes the shape and dimensions of the components of SY Muscae. The result of the analysis is a model of light curves, radial velocity, and a set of SY Muscae physical parameters. Based on the comparison of the results obtained by us with the results in the literature, it turns out that SY Muscae is a typical symbiotic star.
Dust production in galaxies at z > 6
Dust production is a very important issue in galaxy evolution. Unfortunately, we are still unable to determine its formation mechanism. I will present the investigation of dust production in nine galaxies at the redshift at z > 6, for which dust emission has been detected. In recent years, more accurate measurements were made using the most powerful instruments, eg ALMA, which contributed to better estimates of luminosities and sizes, and thus to determine the masses of gas, dust and stars in the studied galaxies. We conclude that asymptotic giant branch (AGB) stars did not contribute to the dust formation significantly in these Early Universe galaxies, and that supernovae are unlikely to produce the bulk of the dust mass. I will discuss how the advent of future large telescopes will contribute to this topic.

Star formation and physical processes in local galaxies at low radio frequencies
The new continuum radio surveys delivered in recent years are an outstanding resource in addressing long-standing questions in modern astrophysics. In this talk I will focus on the lowest radio frequencies (<230MHz) currently accessible with the ground based new-generation radio facilities. Specifically, I will present our recent results on radio spectral energy distributions and star formation of Sculptor Group galaxies and Magellanic Clouds, which we observed with the Murchison Widefield Array (MWA) — a low frequency SKA precursor from an Australian outback. Although of low angular resolution, especially as compared to ALMA, these sensitive low frequency observations are very complementary to GHz observations, and necessary for a complete picture of physical processes occurring in galaxies.

Applications of Machine Learning to Asteroid Shape Modelling — conclusions from the NASA Frontier Development Lab
In the summer 2017 I was involved in the NASA Frontier Development Lab, an intense 8-week study concentrated on tackling topics important to NASA using machine learning tools. During the programme interdisciplinary teams of early career researchers were looking at issues related to planetary defence, space weather, and space resources. The team I was a part of investigated shape modelling of near-Earth asteroidsfrom radar data. These asteroids are the Earth's closest neighbours in space, most accessible by space flight and with a potential for causing a threat to the planet. Even though they are constantly monitored, detailed characteristics, like shapes and sizes, are available for only a selected few. Physical models are required to successfully plan spacecraft missions and set up impact mitigation strategies. Additional incentive is in learning know how our space environment works and evolves. Reconstructing asteroid shapes and spins from radar data is, like many inverse problems, a computationally intensive task. Shape modelling also requires extensive human oversight to ensure that computational methods find physically feasible results. In this talk I will discuss the results of our work at NASA Frontier Development Lab 2017, exploring the application of machine learning tools to the shape modelling task.

In years 2015-2017 we have conducted a programme of high-resolution spectroscopic observations of a sample of detached eclipsing binaries (DEBs) observed by the Kepler satellite in its original mission field. With the 1.88-m telescope of the Okayama Astrophysical Observatory and its HIDES spectrograph, we have collected 290 spectra of 23 systems, in order to analyse them thoroughly and as comprehensively as possible. The sample contains variety of different objects (giants, low-mass stars, multiples, pulsators, planet hosts), many of which were studied for the first time, and with parameters derived very precisely. In my semi-formal talk I will present a subjective selection of 10 systems from our sample that I find the most interesting, intriguing and important for the stellar astrophysics.

Young asteroid families: following AMC inspiration
Asteroid families are clusters of small bodies that move about the Sun on fairly similar orbits. They are outcome of a collisional disruption of a common parent asteroid. Therefore, analysis of members in families can bring us interesting information about the fragmentation process at high-energies and, otherwise inaccessible, interior properties of asteroids. The most valuable in this type of studies are young families, in which the evolutionary processes had not enough time to confuse the results. I will review the past two decades of a race to find ever younger families in the main belt, demonstrating also what kind of unexpected results it brought along.

Problems with interpretation of egzoplanetary signals in the lightcurves of the sdBV and sdO subdwarfs from the Kepler field
We are showing that some of the exoplanetary signatures found in the light curves of a couple of sdBV star systems (KIC 5807616 and KIC 10001893) might be of different source than exoplanet light reflection or radiation effects. We point out that at least one signature can be explained by a combination of pulsating frequencies of the host star and others might be just artifacts. Using simulated light curves we also analyzed frequency changes of the signal around 0.256 c/d (~3.9 day) visible in the Fourier transform of the KIC 10449976 sdO star light curve. Our simulations show that it is difficult to reproduce the observed signal frequency variations by the weather changes in the exoplanet atmosphere.

The Near Earth Asteroid associations
We have made an extensive search for grouping amongst the near Earth asteroids (NEAs). We used two D- functions and rigorous cluster analysis approach.

Designing a global optical satellite tracking network
In recent years European Space Agency (ESA) as well as newly established European Space Surveillance and Tracking Consortium (EU SST) — both of witch Poland is a member state — have increased the effort towards a new satellite tracking system for Europe, that would be independent from external sources of satellite orbital data. Such a system is typically composed of several radar sensors for tracking Low Earth Orbit (LEO) satellites and several optical sensors for higher orbit targets. However recent developments in optical telescopes enabled an efficient tracking of LEO satellites with an equipment 2 to 3 orders of magnitude cheaper than a typical satellite radar. Of course optical satellite sensing suffers from a daytime and bad weather limitations to a much greater extent than a satellite radar. Therefore it is reasonable to simulate an optical satellite tracking network, using a global cloud-fraction statistics, in order to estimate possible outcome from such an entertainment. In this seminar I present preliminary results of simulations showing weather it is possible to build an efficient global optical satellite tracking network, what locations should be selected on Earth, and how many sites should be used in order to have a very high probability of observing each target every day.

Galaxies in the large scale structure at z∼1
I will present recent results from the VIMOS Public Extragalactic Redshift Survey (VIPERS). VIPERS – with its \sim 90,000 spectroscopically measured galaxies, a large volume (5 x 10^7 h^(-3) Mpc^3), and an effective spectroscopic sampling > 40% – can be considered the state-of-the-art counterpart of "local" (z<0.2) cosmological surveys but targetting the epoch at z \sim 1. I will summarize our newest results on the properties of galaxies and large scale structure and their common evolution since z \sim 1. How galaxies changed during the last 8 bln years? What are the properties of the 3D cosmic structure emerging from VIPERS measurements and what they can they tell us about cosmological parameters? And, most interestingly – what remains unknown and why do we need even larger surveys in the future?

Uncertainty assessment of asteroid models from disk-integrated visual photometry
The volume of an asteroid shape model, when combined with the size and mass estimates, is essential in bulk density determination – one of the most important physical parameters that allow us to peek inside asteroids and make conclusions about their inner structure. The shape model uncertainty propagates to volume, and analogously to any
other property determined from the model, affecting every conclusion drawn for a population of small bodies under scrutiny. There definitely exists a compelling need for a procedure of quality and uncertainty assessment of asteroid models. I would like to present modelling-technique-independent uncertainty assessment method based on gen-
erating clones of investigated model. By far, the most abun-dant data type for the most numerous target sample is disc-integrated relative photometry in visual bands and the majority of published asteroid models are based solely on it. For that reason the presented method deals with photometric lightcurves and absolute sparse data.

A Tale of Massive Pairs
Several aspects of stellar evolution can be tested with B-type stars in eclipsing binary systems. Finding tighter constraints on the value of the convective core overshooting parameter is one of the most valuable among them. Precise photometry and high-resolution spectroscopy with high SNR are required to achieve that goal, but since many of the targets are bright enough, the challenge is fair. The approach to examine the aforementioned aspect of stellar evolution using observations of B-type stars obtained with a wide range of spectrographs, as well as BRITE-Constellation satellites, will be presented.
Testing the disk instability model of cataclysmic variables
The disk instability model attributes the outbursts of dwarf novae to a thermal-viscous instability of their accretion disk, an instability to which nova-like stars are not subject. We aim to test the fundamental prediction of the disk instability model: the separation of cataclysmic variables (CVs) into nova-likes and dwarf novae depending on orbital period and mass transfer rate from the companion. We analyse the lightcurves from a sample of ~130 CVs with a parallax distance in the Gaia DR2 catalogue to derive their average mass transfer rate. The method for converting optical magnitude to mass accretion rate is validated against theoretical lightcurves of dwarf novae. Dwarf novae (resp. nova-likes) are consistently placed in the unstable (resp. stable) region of the orbital period – mass transfer rate plane predicted by the disk instability model. None of the analyzed systems present a challenge to the model. These results are robust against the possible sources of error and bias that we investigated. The disk instability model remains the solid base on which to construct the understanding of accretion processes in cataclysmic variables.

Exploring the free-floating planet population with the OGLE data
Theories of planet formation predict the existence of a population of unbound (free-floating) planets. Gravitational microlensing provides a unique tool for studying these objects. The first results of Sumi et al. (2011) claimed that Jupiter-mass free-floating planets are as common as main-sequence stars. However, these results appear to disagree with censuses of substellar objects in young clusters and star-forming regions and with predictions of planet formation theories. I will present new results of the analysis of a ten times larger sample of microlensing events discovered by the OGLE-IV survey during the years 2010-2015. They shed new light on the population of free-floating planets.

Extended Lissajous-Kustaanheimo-Stiefel transform
Kustaanheimo-Stiefela (KS) transform is used to regularize and linearize Kepler problem and t transform it into harmonic oscillator. Regularization changes the independent variable (time) and can improve accuracy of numerical propagation of orbits, especially when eccentricity is high. Lissajous variables are used as action-angle variables for harmonic oscillator. In my presentation I will show these two transforms using canonical formalism and extension for orbits with explicit time dependent perturbation.

Planets around other suns
Stars beyond the MS are frequently avoided in planet searches because they are known to exhibit various types of variability: RV variations of unknown origin were pointed out to be common in red giants (RGs) by Walker et al. (1989), and multiple pulsation modes are often present. In addition, the rotation of starspots across the stellar disk can affect the spectral line profiles of these stars (Vogt et al. 1987; Walker et al. 1992; Saar & Donahue 1997). However, soon after the first discovery (ι Dra b Frink et al. 2002), searches for planets around stars beyond the MS have become recognised as important in building a complete picture of planet formation and evolution for several reasons. First, they allow extending the reach of the most versatile RV technique, which is not applicable on the MS because of the high effective temperature of the stars and their fast rotation rates, to objects with masses significantly higher than solar (e.g., o UMa, a 3 M⊙ giant with a planet – Sato et al. 2012). Second, the planetary systems around evolved stars are much older than those around MS stars, and therefore they are suitable for long-term dynamical stability considerations. Planetary systems around giants are also subject to changes induced by stellar evolution, and therefore are suitable for studies of star – planet interactions, and last but not least, evolved planetary systems carry information on the initial population of planetary systems to be found around white dwarfs. It is no surprise then that several projects devoted to searches for RV planets that orbit RGs were launched. One of the largest of them is the PennState – Toruń Centre for Astronomy Planet Search (PTPS, Niedzielski et al. 2007; Niedzielski & Wolszczan 2008a,b).
In my talk I will present the sample of PTPS, current status of our planet search and the most recent discoveries. I will also discuss some properties of the exoplanets around evolved stars from the PTPS perspective.

ATHENA - exploring the hot and energetic Universe
X-ray astronomy requires satellites to make progress in searching the distribution of hot matter in the Universe. Approximately 15 years period of time is needed for full construction of the flight instrument from the mission concept up to the launch. A new generation X-ray telescope ATHENA (the Advanced Telescope for High Energy Astrophysics) was approved by European Space Agency as a large mission with a launch foreseen in 2028. I will talk about how ATHENA will help us to study Hot and Energetic Universe, and I will present Polish involvement to the mission development.

Asteroid disruptions today
Disruptions of asteroids are often viewed as ancient events leading to the
formation of asteroid families and pairs, binary and multiple systems, and
discrete dust bands within the Zodiacal cloud. But thanks to the
remarkable progress in solar system science over the last decade, we can
now directly observe asteroidal disruptions occurring before our eyes.
Various lines of evidence suggest that the disruption can be a consequence
of a rapid rotation resulting from a long-term spin-up, or a result of a
hypervelocity collision with another minor object. Up until recently the
two mechanisms were difficult to distinguish because of the unknown
rotation rates of the disrupting small asteroids, but this has changed
after our team investigated the recently disrupted asteroid P/2012 F5.
Using the Keck II telescope atop Mauna Kea we discovered several fragments
of the object and obtained the highly anticipated measurement of the
rotation rate, which turns out to be the fastest known among active
asteroids and is fast enough to support the rotational disruption
scenario. Further observations with the Hubble Space Telescope have
revealed that the system is in fact the first ultra-young asteroid family
identified to date, and given its likely formation via rotational
disruption, it can also be the first known asteroid family of
non-collisional origin.

Determination of atmospheric parameters for stars from the multiple systems
We would like to present results for the two objects, GT UMa B which is a part of multiple system and for the eclipsing binary star BD-00 2862. The spectra for the first object were obtained with the spectrograph ESPERO mounted on the 2-m telescope in Rozhen and for the second one with PST1 (Poznań Spectroscopic Telescope 1) located in Borowiec. For those stars we estimated atmospheric parameters, such as: the effective temperature, surface gravity, metallicity and the projected rotational velocity. The observed spectra were compared with the set of synthetic spectra calculated with the iSpec code.
BEANS -- my new shiny 'telescope'
The amount of data in science which is delivered nowadays increases like never before. It applies for all fields of research. However, physics and astrophysics appear to push the requirements for data storage and analysis to the boundaries. With already existing missions like Gaia and for future projects like LSST the need for reliable and scalable data storage and management is even higher. The amount of data for many projects is too big for simply processing with bash or python scripts. Tools which would allow easy data analysis are crucial in research these days.
BEANS software is a web based, easy to install and maintain, new tool for interactively distributed data analysis. It provides a clear interface for querying, filtering, aggregating, and plotting data from an arbitrary number of datasets and tables.
During the seminar I will present features of the BEANS software and show how it can help scientists to analyze huge datasets.

SANORDA - WP1200 Historic orbits database
SANORDA (Service for Archival NEO Orbital and Rotational Data Analysis) is an ESA funded project aimed at archiving light curve and orbital data. In work package WP1200 we focus on determining historical orbits of all NEOs to reproduce their orbital improvement history starting from discovery onwards. The historical orbits may aid better observation planing and improve our understanding of astrometric biases present in the Minor Planet Centre database. We focus on two orbit computation methods: the ranging method and the traditional linearised least squares method. For asteroids with short observational arcs (shortly after discovery) we use ranging method and when the phase space of possible orbital solutions is sufficiently contained (close to Gaussian distribution) we switch to least squares. Those orbital histories are being reproduced for around 17 000 NEAs, which will result in almost 2 000 000 orbits. The project is ongoing and the final database is expected in 2018.

Michael Ruppert is an independent journalist who has made a minor career out of telling people news that most folks do not want to know. Ruppert, a former police officer, predicted the Wall Street debacle of 2008 several years before the fact, at a time when most analysts were still imagining infinite growth for the stock market and major investment banks. Since then, his vision of the world's future has grown only darker. As Ruppert sees it, civilization and the global economy has yet to wean itself off fossil fuels, and when the world's supply of oil finally runs out, it will lead to a global financial catastrophe that will leave no one unscathed. But while most of what Ruppert has to say bears the ring of truth, there's a small audience for his dire message -- the primary medium for his work is a self-published newsletter, and his most recent book has done so poorly in the marketplace that he faces eviction from his home. Is Ruppert right? And if he is, why doesn't anyone care? Filmmaker Chris Smith profiles Michael Ruppert and gives him a chance to explain his apocalyptic vision of the future at length
The story of Energy
Professor Jim Al-Khalili discovers the intriguing story of how we discovered the rules that drive the universe. Energy is vital to us all, but what exactly is energy? In attempting to answer this question Jim investigates a strange set of laws that link together everything from engines to humans to stars. It turns out that energy, so critical to daily existence, actually helps us make sense of the entire universe.
Series: Order and Disorder
Hosted by ABC journalist Bob Woodruff, this two-hour special explores what a worst-case future might look like if humans do not take action on current or impending problems that could threaten civilization. The problems addressed in the program include climate change, overpopulation, and misuse of energy resources. The events parallel the life of a fictitious storyteller, 'Lucy' as she describes how the events affect her life. The program included predictions of a dystopian Earth in the years 2030, 2050, 2085, and 2100 by scientists, historians, social anthropologists, and economists, including Jared Diamond, Thomas Homer-Dixon, Peter Gleick, James Howard Kunstler, Heidi Cullen, and Joseph Tainter. According to Executive Producer Michael Bicks, "this program was developed to show the worst-case scenario for human civilization. Again, we are not saying that these events will happen — rather, that if we fail to seriously address the complex problems of climate change, resource depletion and overpopulation, they are much more likely to happen.

We have canvassed the world in search of the best and most fascinating science and tech stories of the year for 2015 YEAR IN SCI-TECH". This action-packed hour of fun and intrigue revisits the world's first glimpse of Pluto and images of water on Mars while exploring what this all could mean for intelligent life in the universe – all while earthling's inch closer to becoming actual space tourists. Throughout the hour, we revisit the year's most amazing techological feats and scientific discoveries, including new and elusive animal species discovered deep under the ocean, as well as the hottest tech trends – from hover boards to driverless cars and trucks, and the newest advances in mind-blowing virtual reality.
When Will Time End
Discover the Eras of the Universe and the answer to this big question: When Will Time End? Once the notion that the universe started with a rapid inflation nicknamed the Big Bang became accepted by the majority of scientists, many possible fates are predicted by rival scientific hypotheses, including futures of both finite and infinite duration. The ultimate fate of the universe is dependent on the shape of the universe and what role Dark energy will play as the universe ages.

Background: Structural abnormalities predispose congenitally bicuspid aortic valves (BAV) to early stenosis, but tricuspid aortic valve (TAV) stenosis is associated with cardiovascular risk factors. We hypothesize that TAV aortic stenosis (AS) is associated with more cardiovascular risk factors and worse outcomes after aortic valve replacement (AVR) compared with BAV AS in an age-matched cohort.
Methods: From 888 consecutive patients undergoing AVR for severe AS between January 1, 2010 and December 31, 2012, an age-matched cohort of 198 TAV AS patients and 198 BAV AS patients was identified. All valves were categorized by cardiovascular pathologists.
Results: Table 1 shows characteristics prior to AVR. Five-year survival following AVR was lower in TAV compared to BAV (61 vs 79%, p=0.02). Univariate predictors of mortality after AVR were TAV (p=0.02), dialysis (p=0.02), ejection fraction (EF)<50% (p<0.0001), and Charlson comorbidity index (CCI) (p=0.01). In multivariate analyses, only the CCI and EF<50% remained significant. Survival following AVR for BAV AS was not different than expected (p=0.17), but was worse than expected for TAV AS (p<0.001).
Conclusions: TAV is associated with increased prevalence of cardiovascular risk factors compared to BAV at the time of AVR for severe AS. This suggests AS develops due to an adverse milieu in TAV whereas in BAV it is likely due to flow shear stress. Survival normalizes after AVR in BAV but excess mortality in TAV is related to comorbidities and impaired EF.

Data analytics software provides a treasure trove of information for video game publishers and developers. The video game industry is massive, given that in 2017 alone the industry generated $108.9 billion in revenue. Furthermore, revenue is expected to grow to $128.5 billion by 2020.
This staggering amount of revenue generated indicates that there are billions of gamers playing video games and generating terabytes of data. Therefore, video game publishers and developers must take full advantage of this information treasure trove to improve game design, business models and marketing efforts.
With that in mind, the following sections dive into three ways data analytics software is improving video games.
Graphics, storytelling, and creativity are no longer enough. To keep gamers engaged, developers have to tailor the game to how players behave. Developers have to know how gamers are using the game systems, interacting with levels, how much time they spend playing, when do players drop off, and why do they drop off. The information is particularly important for multiplayer games, where gamers tend to exploit bottlenecks in a level, or flaws in a system can kill player engagement.
If developers have information on hand, they can make adjustments to correct mistakes, improve gameplay and keep player engagement up. Data analytics software platforms record the actions of millions of players and generate meaningful information on how players behave, in the game itself. Data analytics software is particularly useful because developers can gather real-time information on player activities. Therefore, developers don't have to rely on community feedback nor do they have to wait till a problem becomes a serious issue to take action.
Instead, developers can monitor player movement in real-time, identify a flaw and take action to fix it almost immediately. Hence, game developers have more than just creativity in their hands – they have data on player behaviour.
Data analytics helps publishers make informed decisions about long-term business models. With data analytics, publishers will know which games are popular, why are they popular and how to use data to improve their own games. An excellent example is popular freemium games, like Fortnite and PUBG. Publishers can use data analytics to see what is drawing players, why they spend money, how much time is spent on the game, and more. The publisher can use this information to inform their own business strategies and long-term business models.
Publishers will be taking a long-term approach to business planning. Hence, we will see publishers shifting away from short-term profit strategies towards long-term business models. An excellent example is Microsoft' acquisition of Minecraft in 2014, it was a decision that raised many eyebrows. However, having sold more than 122 million copies, and a monthly player base of 55 million, Minecraft has thrived under Microsoft. Furthermore, the software giant announced their plans to make Minecraft a 100-year brand.
Marketing is a crucial component of any industry – specifically, the video game industry.
Therefore, it's important for game marketers and advertisers to make a strong impact if publishers want to enjoy strong sales. If gamers are exposed to adverts not relevant to them, they will not make additional purchases, thus wasting resources. Therefore, its important for gamers to see adverts that are relevant to them. Hence, publishers need to segment their audience, according to location, preferences and more. But how do publishers segment an audience of millions? Easy – data analytics.
Powerful analytics platforms like SAS can segment an audience according to any variable. Thus, publishers can segment their audience and craft ads that resonate with each segment. Developers can look at who is playing the game for a long time or spending the most on microtransactions, and what is prompting their actions. This information can then be used to develop programs that will incentivise other players to spend more money. Similarly, publishers can create loyalty programs to reward certain players.
The video game industry is now worth a billion dollars, however, there is potential to generate more money with data analytics. By using powerful data analytics platforms, publishers can discover new ways to market games through better audience segmentation. Moreover, developers can improve player retention by constantly improving the game.
Data analytics software provides real-time information on how players play the game, which can be used to improve the gameplay experience. Gamers create at least 2 terabytes of data a day when playing video games. Rest assured, publishers and developers who don't make full of use the information will fall behind.
