We selected a ducted heating and cooling heat pump solution from Key Heating. Alex, Aban & Andrew installed the duct work. I can't say enough about the quality job that they did. They worked with us to minimize the impact of the ducts on our basement and attic. They showed up early each morning and completed their work ahead of schedule. The work was done very professionally. They cleaned up after each days work so much so that I didn't have to do any additional clean up. And they were the most courteous work crew I have experienced. My hats off to this crew!

Key Heating and Air Conditioning installed a new Heat Pump and backup furnace system for me this winter. I am very pleased with the job that they did. The HVAC system works great and it has been saving me a lot of money. I recommend Key for new HVAC system installation.

We had a great experience using Key to install a new furnace, heat pump and duct work to our home. Everyone from the office staff to the field guys were very responsive to all of our questions prior to the installation through completion. Jon presented us with several options for heating and cooling and explained the pros and cons of each, helping us make the right choice for our home. We would definitely recommend using Key Heating and Cooling! Thanks guys!!

Keith P was fantastic. Very personable and extremely knowledgeable. I had double trouble - furnace fan had died, as had the hot water pressure valve. He explained everything in layman's terms and though he had to leave and return with another part several hours later, he was just as pleasant at the end of the day as he was when he walked in the door that morning. Would totally recommend Key Heating & AC in general and Keith P in particular. In addition, the office staff is terrific - both Laurie and Karen were wonderful.
By Janet S. on 03/13/19
Walter was pleasant, professional and prompt! Diagnosed the problem quickly and the repair was done ASAP. We have a geothermal system that requires a different diagnostic skill set from our oil based system. Key technicians have this knowledge and are always able to answer questions.
By Matt F. on 03/08/19
Walter was punctual, knowledgeable, and was able to resolve our issue quickly. He didn't seem to mind me observing his work and asking questions, which was nice. He clearly explained the issue, how he resolved it, and a plan of action to move forward.
By John J. on 03/08/19
Fabulous work! Great Customer service. I highly recommend to anyone. Do yourself a favor and call them. Don't waste time with anyone else. Keith P. Was amazing and will be looking forward to seeing you in the fall.

Keith did a wonderful job explaining what was going on with my furnace. Taking the time to go over how when hearing loud banging noises from the furnace means there is air in the lines. Keith was quick to fix this problem and pointed out some potential parts should be replaced at the next cleaning. Very please. Scheduling Dept. was very quick to get me scheduled for an appointment too. Great team work all the way around.

Field technicians are excellent. Courteous, thorough, obviously familiar with equipment and know what they are doing. 5 stars! Pricing seems reasonable. Unfortunately, the scheduling, communication and follow through on appointments is very unreliable. Recent appointment was three reschedules....2 at last few hours - and one after a no show. Email communications are late (several days after appointment). Office seems to struggle with technology....How about texting regarding service changes? Each of those 3 times I rearranged my work day to be home...so it ends up being costly I struggle with giving a combined rating...I would say technicians 5 and service/scheduling/communication 2... Bring that end of the business up to par and I would say 5 star

After some back and forth with two other outfits, Key diagnosed the problem and, after getting the parts, quickly fixed the situation.

I have been dealing with Key Heating for several years and I don't know what I would do without them. They are professional, helpful and I can now heat and air condition my house very economically. I would recommend them to anyone who would like to pay less to stay warm or cool.

I have had somewhat mixed results with Key Heating; some good, some not so good. My last experience with Richard was one of the positive ones. It's not the quality of the service that I've had problems with, its the communications within the company that have left me frustrated, to the point where I've considered looking for someone else to provide my service requirements. However, Richard has left a very positive feeling with me and hope this is a move in the right direction towards better communications.

We had our annual furnace cleaning conducting by Key Heating. Richard was out technician. He was very professional and easy to communicate to. He answered every question I had, and went above and beyond to make sure my home was ready for a cold winter. I appreciated his recommendations and honesty while discussing our system. Its very clear that Richard (and the rest of the team we dealt with) was very knowledgeable and really takes pride in the work that he does, no matter what challenge arises.
I needed Richard to inspect previous work. He thoroughly inspected the work and provided a clear explanation.

Your guy was here two mins later anyway, Richard. And he is great by the way. I appreciate how you guys offered him to come early but didn't jam that at me and I appreciate how thorough Richard was on top of him taking the time to explain things to me as well as his general kindness and manners while visiting our home that had a barking dog two little kids and a couple of other adults at the same time!

This is a great route if you are looking for a little adventure but don't have the time available for a longer trip. The trip starts at the Wolverine airstrip, elevation 5000 ft. There are two ways around the big mesa, one shorter and the other more scenic. Once around the other side you drop down into Doubtful Creek. A steep walled canyon in Doubtful forces you to take an adventurous detour over a rock glacier before dropping back down to the creek and then all the way down to the headwaters of the Nizina River just below the glacier.Streams: Route includes stream crossings. Be prepared and knowledgable about safe crossing techniques.

Richard Blackford Pietà
Commissioned jointly by the Bournemouth Symphony Chorus and St Albans Choral Society
Wolfgang Amadeus Mozart Requiem in D minor, K626
Date: Saturday 25 April 2020
Time: 7.30pm
Daisy Brown soprano
Rebecca Afonwy-Jones mezzo-soprano
Bradley Smith tenor
James Platt bass
Felix Kemp baritone
Amy Dixon saxaphone
George Vass conductor
The Purcell School Chamber Choir
Orchestra Nova accompanying orchestra
St Albans Choral Society continues its 75th anniversary season with performances of two major works – Richard Blackford's critically acclaimed Pietà and Mozart's profound setting of the Requiem text.
The core of Blackford's Pietà is the Stabat Mater, the 13th-century Christian hymn to Mary, but the composer also sets poetry by acclaimed Russian writer Anna Akhmatova. The poems echo the words of the Stabat Mater reflecting the grief of Akhmatova for her son Lev, a student at Leningrad University, who, in 1938, at the height of Stalin's terror, was arrested and shipped to an Arctic labour camp. For 17 long months Akhmatova wrote letters to officials beseeching them to tell her the fate of her son – her struggle is immortalised in the poetry-cycle Requiem. Alternating between elegy, lamentation and witness, it culminates in this truly desperate stanza:
For seventeen months I've been crying out,
Calling you home.
I flung myself at the hangman's feet,
For you my son, my horror.
Scored for mezzo-soprano and baritone soloists, chorus and string orchestra, the work also includes an important part for solo saxophone, to be performed by Australian virtuoso, Amy Dickson. In Pietà, Blackford perfectly embraces the Stabat Mater text and the passion of Akhmatova's words.
The programme concludes with Mozart's transcendent setting of the Requiem which, though left unfinished at his death, is the composer's one true choral masterpiece.
St Albans Choral Society is one of Hertfordshire's leading amateur choirs; it gave its first concert in December 1944 and since then has performed a huge part of the repertoire with music ranging from the Baroque to the present day. The Society has an enviable reputation for the commissioning and performance of new work and enjoys a fruitful relationship with Orchestra Nova, its regular performance partner.
Recent repertoire has included the Requiems of Fauré and Duruflé, Handel Messiah and Dettingen Te Deum, Mozart Mass in C minor, Beethoven Mass in C, Britten St Nicholas and work by contemporary composers James Francis Brown, Gabriel Jackson, Cecilia McDowall, Tarik O'Regan and Pēteris Vasks.
Firmly rooted in the local community, the society has also been involved in education outreach with local primary schools and the choir's singing group regularly performs to people in senior living accommodation who are unable to attend concerts.
Celebrated British conductor and festival director, George Vass, was appointed music director of the choir in 1994; in 2017, he was presented with a BASCA Gold Badge Award for his support of the British song-writing and composing community.

USMNT U-23 prospect Sabbi signs pre-contract with Odense
By Larry Henry Jr. January 7, 2020 4:13 pm Follow	@lhenry019
By Larry Henry Jr. | January 7, 2020 4:13 pm	Follow @lhenry019
Emmanuel Sabbi will be trading Hobro for Odense this upcoming summer.
Fellow Superliagen side Odense announced Tuesday that Sabbi will join the club this summer, after signing a four-year pre-contract on Tuesday. Sabbi, a U.S. Under-23 Men's National Team prospect, will finish the current Superliagen season with Hobro before making his move to Odense.
"He's an a huge explosive player, who is good one against one," Odense sporting director Jesper Hansen said. "He is very exciting and has the one X-Factor which makes him unpredictable for all opponents. We saw for ourselves how good he is when we beat Hobro 2-1 in the fall, where he scored a very nice goal directly on the free kick."
"He is dynamic in his playing style and in that way he fits well with the way we play. He has made it in Hobro, where he is a big profile and has really lifted his game since coming to Denmark two and a half years ago. Despite his young age, he has a lot of experience in the Super League, and there is potential to develop even more in OB. We look forward to seeing him unfold in the striped jersey."
The 22-year-old scored eight league goals last season, including three in four appearances in the relegation playoffs. He currently has six goals this season in 16 appearances in all competitions. Sabbi has also made a pair of appearances for the USMNT U-23's in 2019 and is an option for Jason Kreis' side ahead of Olympic Qualifying.
"I feel it is a natural step for me to take," Sabbi said. "I really like the way Odense plays. You emphasize having the ball in your own ranks and playing very directly. It has always been difficult for Hobro when we have met OB, because they have many good players and they are always in control. It's going to be great to be a part of it."
"I like the way the coaches are towards the players, so I look forward to working with them. I had a number of other clubs that were interested, but I chose OB because they showed a genuine interest in having me on the team. It will be a new challenge and I love it. I have to contribute hard work and try to show my worth one against one where I have to challenge with my speed."
Odense is currently ninth in the Superliga, while Hobro are bottom of the table in 12th. Both teams return to league play in mid-February.

Q: Bitmap factory Memory error with smaller images? Hoping someone can help me solve this.
Im making a very simple game on android 4.2.2 using just UI elements, ie no 3D, opengl, Just as a challenge really but I've ran into a little head ache.
I was having O.O.M issues with loading graphics (to be expected with android) so i looked for other routes and found bitmap factory and decided to use a simple implementation. with my images i was hitting up to 40mb allocated memory during game play so I reduced the files from 1080x1920x4bit to 540x960x4bit in a hope to reduce memory load but now it reaches up to 72mb during game play.
Am i missing something or is me thinking, halve the size of images and halve the memory usage? or does upscaling use that much more?
is there any way I can reduce this amount of memory down to a decent 16-20mb range?
Notes on the APP.
all images are stored in res/no-dp or res/xxdpi. And are all jpegs.
I have six pop up images which are 100x100dp jpegs and 5 x Life segments which are 50x50dp
this is the code im using to load the images from bitmap factory
Bitmap bMap = BitmapFactory.decodeResource(getResources(), R.drawable.dummy1nn);
             button7.setImageBitmap(bMap);

and im loading the other images as background resources for now via buttons or image views.
I also have soundpool running on elements and a timer.
Any help would be appreciated. I dont want to post all my code as it is a right mess at the minute as im trying many different methods to get this working smoothly. The only issue i have is the memory load.
My current memory after running the game and letting it sit for 5 minutes is:-
Heap size - 73.086mb
allocated - 70.40mb
free -  2.625mb
used - 96.41%
objects - 47,161
I'm using LG Nexus 5 'hammerhead' as DEV device with unlocked bootloader and stock rom.
Thanks guys. :)
edit:
Answer was to use picasso, although there are a few image libraries out there i liked the simplicity of picasso a lot. and always use MAT when using images to make the relevant changes to quality/size and format to get the lowest memory print (mine dropped to 26mb peak)
have fun

A: Picasso is a really good library that will handle memory management, asynchronous loading, and caching for you.
Using your example, it would be used simply like this:
Picasso.with(this).load(R.drawable.dummy1nn).fit().into(button7);

The Last Cowgirl (Fiction) Jana Richman (William Morrow, $24.95), Hardcover.
In this contemporary Western, young Dickie Sinfield and her family move away from their comfortable urban lifestyle to a Utah cattle spread. They discover a loony hermit built the ranch house they bought, which includes a pig room where the old man slaughtered hogs. Dickie unwillingly experiences roundups and rodeos, and dines with the family on their 4-H calf. Emotional turmoil is chronicled from Dickie's point of view as she grows up struggling to make sense of loss, broken hearts, betrayal by her best friend, her father's temper and her mother's infidelity. Wonderfully written, this evocative and memorable story brings laughter as well as tears.

Homeowners across the United States can experience rodent problems just about any time of year, but it is in the fall that rodent infestations become more common. The reason for this is because the weather is getting cooler, and they know that they need a warm place to hunker down for the long winter months. They also need a place that has access to food and water, which is why they find a way to get inside homes. The most common house-invading rodents are house mice, field mice, Norway rats, and roof rats, and they can enter through very small holes and gaps with ease.
Rodents are dangerous since they carry germs on their bodies, and in their urine and feces, that can cause diseases such as murine typhus, leptospirosis, and Salmonella. They can also do a lot of damage to a home and personal belongings, including electrical and plumbing damage by chewing through items, wires, and pipes.
At the first sign of any rodent activity, you should contact a professional pest control service immediately. As a homeowner, you need to know where to look and what signs to look for. Here are a few helpful tips to get you started with how to tell if you have a rodent problem this fall.
You should look for paired tooth gnaw marks that are about ⅛ of an inch wide, rice-shaped dark droppings, and any type of damaged food packaging. To look for these signs, check along baseboards, window and door frames, kitchens, pantries, and cabinets, as well as inside drawers and other contained areas. They may be nesting in the attic, wall voids, spaces behind appliances, and under furniture, as well as in storerooms, closets, boxes, and shelves. And take note that you may never see a rodent because they are great at avoiding detection. You might just hear them scratching or gnawing from their hiding places.
If you think or know you have a rodent infestation in Western Massachusetts or Hartford County, CT, call on the experienced technicians at American Pest Solutions. Our experienced technicians can find where the rodents are and get rid of them and keep them out. We start with a thorough inspection then move on to effective removal and treatment, and continue providing ongoing protection. Give us a call today for more information on how we eradicate rodent problems for homeowners.

I just found out that both of these companies are owned by the same company in the U.K.and was wondering why they sell the same TEFL products under two different names. It makes me suspicious. What do you guys know? Have you dealt with them before?
Many companies have the same owners, as it is common practice to invest in companies with similar products. Did you know that Tesco owned Dobbies until quite recently; I wonder what scams they were running? Incidentally, Tesco is a British multinational grocery and general merchandise retailer and is the third largest in the world. Dobbies is a British chain of garden centres and one of the largest in the UK.
Methinks, you already know the answers to your questions and are just using the forum to stir it up, as usual!!!
This company or rather these companies look to be huge and spend a fortune on advertising. I was called by both of them a few times in the last year but I enrolled at a TEFL program at a local university for only $200 so I did not spend any time talking with the UK sales reps.
But I was annoyed that they lept calling me a few times even after I told them I was already taking a TEFL program, and their last call was to sell me on a China teaching internship which made no sense to me. I mean it is so easy to get a real teaching job for at least 15,000 a month in China, why the hell would anyone want an internship that pays only 6,000 a month? Ridiculous!
As I read these complaints it seems they are mostly about misrepresentation and deceptions. Truthfully, I am glad I got my TEFL course from a real university that is over 100 years old.


The flip side may be that O'Shea and Abrahams will return to their clubs for their U23 games.
Not sure they would - different loan rules down in Conf South I believe.
2pm kick off. Not actually working this Sunday, but other activities planned.
Ooh, this is exciting, I think I can go to that!
Might have the opportunity to go to that.Have you got a link to it?

I was keeping an eye on their website and it was "TBC" until yesterday, so I think it's probably ok to rely on it. Best keep across the City or Forest websites though, and also take care with the kick-off time. Was showing 1pm for a while in some places, but does now seem to have settled to 2pm.
Would have gone if it had been the City Ground, as have never been there. But Alfreton is too awkward for me on a Sunday.
Gutted that I can't make this.
Will we need to find a right back from somewhere?
Not a bad line up, if a bit young for an U23 game.
Full article now confirming venue and kick off time.

What people looked like a century ago: Modern technology has allowed scientists to get to the bottom of the truth
What did people from the past look like? Most often, the guideline for answering this question are pictures or verbal descriptions in documentary or fiction. But are they objective? Often not, because the artist always conveys his personal perception, and seeks to show the most attractive image. Modern technologies allow to recreate a real image and show what people from the past would look like if they happened to be our contemporaries.
1. King Henry IV of France
Henry IV was the king of France from 1589 to 1610 and was tragically killed during the attack of a Catholic fan on him, died from his knife wounds. Heinrich went down in history as a kind and wise ruler who cared about the welfare of his subjects. The reconstruction of the face of Heinrich was conducted by the historian Philip Frosch, he created a 3D model, based on the preserved skull of the monarch.
2. Ava – a woman from the Bronze Age
The name Ava was given to a woman whose remains were found in a cave by Scottish archaeologists. Project manager Maya Hoole notes that the woman lived more than 3.5 thousand years ago. She was buried in an unusual way – her remains were in a hole dug in stone. Supposedly, Ava could have been an important person, since the arrangement of such a tomb required a lot of time.
Historians have found the preserved bones and recreated the image bit by bit. For example, the jaw was missing, and the size of the lips was calculated according to the thickness of the enamel on the teeth, and on the basis of these data, the depth of the facial tissues was determined. Scientists have determined that Ava's skull was partially deformed, presumably after her death. For what purpose it was done remains a mystery.
3. Egyptian Queen Meritamon
Meritamon was the daughter of Pharaoh Ramses II. Scientists from the University of Melbourne recreated her appearance using data from medical research and computed tomography. From the surviving remains, it was possible to determine that the girl's age at the time of death was between 18 and 25 years old, and she could suffer from anemia. Egyptologists, graphic artists, worked on re-creating the face of Meritamon, paying special attention to the queen's remaining bust and statues depicting it.
4. A man who lived in Dublin 500 years ago.
In 2014, archaeologists in Dublin found the burial of four people, made about 500 years ago. Scientists were able to establish that all four had obvious signs of malnutrition, they were all engaged in hard manual labor and were poor. One of the skulls has been preserved in the best way, according to it, archaeologists restored the image of the Dublin who lived five hundred years ago.
5. Astronomer Nicolaus Copernicus
Nicolaus Copernicus is considered to be one of the greatest mathematicians and astronomers of the Renaissance. It was he who formulated the heliocentric system, proving that the Earth and other planets revolve around the sun. Copernicus died at the age of 70, Polish scientists with the help of modern technology managed to restore his portrait.
6. Jane from Jamestown – Cannibal Victim
Jamestown was the first colony of European migrants who came to settle in America. In 1609-1610, hunger began among the settlers and, according to scientists from the Smithsonian Institution for Natural History, people went to any lengths, even to cannibalism.
In 2012, scientists discovered a find that shocked them. In the garbage pit among the bones of the animals they found … fragments of a human skull. In the course of the research it was established that the remains belonged to a young girl no older than 14 years old, who was killed and eaten in a brutal manner. Traces on the bones of the skull clearly indicated that her body, like a carcass, was torn to pieces and even the brain was eaten, and the bones found suggested that the lower part of the body was carefully divided by the butcher.

'Meat Attraction', the second edition of the Fair of the Meat Sector organized jointly by IFEMA and the National Association of Meat Industries of Spain (ANICE), has closed its second edition with a prevailing international presence in the sector.
The Albacete Emilia Piñero, awarded with the recognition "INTERPORC Promises of the Kitchen"
The Albacete Emilia Piñero has been the winner of the "INTERPORC Promises of the Kitchen Contest", which has cooked, in the opinion of the public and professionals of the hotel trade, the best dishes of "secret ice cream", elaborated mainly with white pig secrecy , caramelized sweet onion and feta cheese.

The meat industry is the fourth industrial sector of our country, only behind the automotive industry, the oil and fuel industry and the production and distribution of electricity. The sector, formed by slaughterhouses, quartering rooms and elaborated industries, has an industrial fabric constituted by near 3,000 companies, distributed by all the Spanish geography, especially in rural areas. Although a significant part of the sector are small and medium-sized companies, this has not prevented the gradual development and consolidation of large business groups, some of them leaders at European level.
In its commitment to a model of sustainable production based, among other aspects, on the integrated prevention and control of pollution, the Spanish pig sector has reduced in recent years by 47% the ammonia emissions per kilo of meat produced, according to data of the National Inventory of Air Pollutant Emissions 1990-2016, published by the Ministry of Agriculture, Fisheries and Food.
The food industry showed a surplus in the 2017 balance of trade of 12,061 million euros, of which 4,564 million euros correspond to the pig sector, which contributes almost 4 out of 10 euros -37.8% -, according to data from the AEAT and the Agrifood Foreign Trade Report published by the Ministry of Agriculture, Fisheries and Food.
The Commission has presented a proposal for a Council Regulation authorizing the opening of negotiations on the distribution of the European Union tariff quotas included in the calendar of the World Trade Organization (WTO).
The pig sector of Spanish white coat closed the year of 2017 with a historical record, which consolidates it as one of the strategic engines of the national economy and as a great world power, thanks to its model of sustainable production. A turnover of more than 15,000 million euros, and exports that totaled 5,022 million euros in 2017, confirm this positive valuation, according to a report of INTERPORC, the Interprofessional of Porcino de Capa Blanca. This organization will once again have an active participation and represent this important economic segment in MEAT ATTRACTION 2018, the Meat Sector Fair. The only Spanish show devoted exclusively to the meat industry, organized by IFEMA and the National Association of Meat Industries of Spain, ANICE, will hold its second edition from September 18 to 20 at the Feria de Madrid.
" This was stated this morning in Madrid by the director of the Interprofessional of Porcino de Capa Blanca (INTERPORC), Alberto Herranz, at the presentation of the closing of the campaign in Spain of the 'PORK LOVERS TOUR 2018', the largest itinerant action of promotion carried out out in the Spanish meat sector.
The Minister of Agriculture, Fisheries and Rural Development, Rodrigo Sánchez Haro, has valued the Porc d'Or Iberian awards as an "incentive" for a sector that contributes 500 million euros to the Andalusian economy. This has been highlighted in Cordoba, during the gala of delivery of the 30 awards of the second edition of this contest organized by the Institute of Research and Technology Agroalimentarias (IRTA), attached to the Generalitat of Catalonia, and which recognizes the results productive activities of Spanish pig farms.

Infertile couples pay £60,000 for a surrogate baby
With UK fertility rates continuing to decline, people are beginning to look to alternative ways of achieving their dream of parenthood. Surrogacy, where an individual carries a baby for the intended parents, is one route which is growing in popularity. Since 2007 there has been a 550% rise in applications for parental orders which are the orders made by a court recognising the intended parents and not the surrogate as the legal parents.
Many couples are wrongly put off surrogacy as they think it will be too complicated or too costly as recently reported in The Times. Couples should not dismiss it without first considering it. Today there are many options available to couples looking to become parents via a surrogate. This is a highly sensitive issue and with careful exploration, couples will most likely find a solution that is right for them whether that be a UK surrogacy through a family member or using a clinic led overseas surrogate. The most important thing that all prospective parents should remember is that the key to being recognised as the legal parents of a child born via a surrogate is to seek competent legal advice at the outset and thereby avoiding the surrogacy pitfalls later on.
If you are interested in learning more about surrogacy or other modern parenting options, then please get in contact with our expert, Sarah Wood-Heath.

\section{Introduction}

The spinning C metric is a boost-rotation-symmetric stationary spacetime of Petrov type D belonging to the Weyl class of solutions of the Einstein equations \cite{ES}. It  can be interpreted as the field of two rotating black holes which are uniformly accelerated in opposite directions under the action of conical singularities.
Using the Boyer-Lindquist-type coordinates $(t,r,\theta,\phi)$ introduced by Podolsky and Griffiths \cite{podgriff1,podgriff2}, the corresponding line element is given by
\begin{eqnarray}
\label{SCmmetric}
\rmd s^2&=& \frac{1}{\Omega^2}\bigg\{\frac1{\Sigma}(Q-a^2P\sin^2\theta)\, \rmd t^2 - \frac{2a\sin^2\theta}{\Sigma} [Q-P(r^2+a^2)]\, \rmd t \,\rmd \phi\nonumber\\
&& - \frac{\sin^2\theta}{\Sigma} [P(r^2+a^2)^2-a^2Q\sin^2\theta]\,\rmd \phi^2 -  \frac{\Sigma}{Q}\,\rmd r^2-\frac{\Sigma}{P}\,\rmd \theta^2\bigg\}\ ,
\end{eqnarray}
where the functions $\Omega$, $\Sigma$, $P$ and $Q$ are defined by
\begin{eqnarray}
\Omega&=&1-Ar\cos\theta\ , \qquad
\Sigma=r^2+a^2\cos^2\theta\ , \nonumber\\
P&=&1-2A{\mathcal M}\cos\theta+a^2A^2\cos^2\theta\ ,  \nonumber\\
Q&=&\Delta(1-A^2r^2)\ , \qquad
\Delta=r^2-2{\mathcal M}r+a^2=(r-r_-)(r-r_+)\ .
\end{eqnarray}
We list in Appendix A the most important properties of this metric.
Units are chosen such that $G=1=c$, so that the parameters $({\mathcal M},a)$ have the dimension of length whereas $A$ of the inverse of length and
$$
\bar a=a/{\mathcal M} , \qquad \bar A=A {\mathcal M}
$$
are nondimensional quantities.

In the limit of vanishing rotation parameter $a=0$ the metric (\ref{SCmmetric}) reduces to the usual non-rotating vacuum C metric, while for $A=0$ we recover the familiar Kerr metric for a rotating source; finally, for either $a=0=A$ or $a=0={\mathcal M}$ we get the Schwarzschild and Rindler solutions respectively.

For a further use it is convenient to introduce the notation
\begin{eqnarray}
\sigma_+&\equiv& (1+a^2A^2)+2{\mathcal M}A=P(\pi), \nonumber \\
\sigma_0&\equiv& (1+a^2A^2)=[P(\pi)+P(0)]/2, \nonumber \\
\sigma_-&\equiv& (1+a^2A^2)-2{\mathcal M}A=P(0).
\end{eqnarray}

We limit our attention to the spherical corona $r_+<r<r_A=1/A$ in which $Q(r)>0$, also implying $P(\theta)>0$ for all $\theta \in [0,\pi]$.
Finally, we require $\phi\in[0,\phi_0)$, with either $\phi_0=2\pi/\sigma_+$ (equivalent to the removal of the conical singularity at $\theta=\pi$) or $\phi_0=2\pi/\sigma_-$ (equivalent to the removal of the conical singularity at $\theta=0$) as explained in Appendix A. In this way there is no need to specify if the removed singularity corresponds to $\theta=0$ or $\theta=\pi$.

We study here massless perturbations to the spinning C metric due to fields of any spin following the
approach of Teukolsky  \cite{Teukolsky,barpre} grounded, in turn,  in the context of the Newman-Penrose formalism \cite{NP,chandra}.
For a Kerr gravitational background Teukolsky found a separable master equation whose eigenfunction solutions essentially solve the problem of the massless perturbations of any spin for the Kerr black hole in terms of gauge- and tetrad-invariant quantities. After that work many authors have discussed generalizations to other interesting spacetimes including the vacuum C metric in standard coordinates \cite{Prestidge}.

We introduce in Section II a master equation for the spinning C metric spacetime whose symmetries allow
the separation of the equation into radial and angular parts, generalizing some previous results valid for the Kerr spacetimes and the non spinning C metric, and use it to study the question of superradiant scattering modes as well as the various allowed coupling terms between the spin of the perturbing field and the background parameters: mass, rotation and acceleration.
Closed form solutions to the radial equation are extensively discussed in Section IV (algebraically special perturbations) as well as in Appendix B (general Liouvillian solutions).

We finally explicitly give in the Appendix C the equations for null geodesics. As in the non-rotating case of the C metric only geodesics of this kind can be separated, because of the existence of a conformal Killing tensor, which is derived too.

\section{Teukolsky Master Equation (TME)}

Consider the spinning C metric in the form  (\ref{SCmmetric}). A Kinnersley-like null frame \cite{kinnersley}
\begin{eqnarray}
\label{frame}
l&=& \frac{\Omega^2}{Q} [(r^2+a^2) \partial_t+ \frac{Q}{\Omega}\partial_r +a\partial_\phi]\ , \nonumber \\
n&=& \frac{\Omega}{2Q} [(r^2+a^2) \partial_t- \frac{Q}{\Omega}\partial_r +a\partial_\phi] \ ,  \nonumber \\
m&=& \frac{(r-ia\cos \theta)}{\sqrt{2}\Sigma \sqrt{P}} [i\Omega a \sin \theta  \partial_t+P\partial_\theta+i \frac{\Omega}{\sin \theta}\partial_\phi ]\ ,
\end{eqnarray}
can be introduced to define Newman-Penrose (NP) quantities.
The only nonvanishing Weyl scalar is
\beq
\label{psi2}
\psi_2=-\frac{(1+iaA){\mathcal M}\Omega^3}{(r-ia\cos\theta)^3}
\eeq
and the only nonvanishing spin coefficients are
\begin{eqnarray}
\label{spincoeff}
\rho&=&\frac{i\Omega(i+aA \cos^2 \theta)}{(r-ia\cos\theta)}\ ,\quad \alpha=\pi-\beta^* +\frac{\sqrt{2P}Ar\sin\theta}{(r-ia\cos\theta)}\ ,
\nonumber\\
\mu&=&\frac{Q}{2\Omega^2 \Sigma}\rho \ ,\quad  \pi=-\frac{\sqrt{P} (r^2A-ia)\sin \theta}{\sqrt{2} (r-ia\cos\theta)^2}\ ,
\nonumber\\
\tau&=& \frac{\sqrt{P}(r^2A-ia)\sin \theta}{\sqrt{2}\Sigma}\ ,\quad \gamma=\mu-\frac{Q_{,r}\Omega -4Q\Omega_{,r}}{4\Omega\Sigma}
\nonumber\\
 \beta&=& -\frac{\sqrt{P}}{2\sqrt{2}}\cot\theta \left(\frac{\rho^*}{\Omega}+A\cos \theta \right)+
\frac{\Omega}{2\sqrt{2}}\frac{(\sqrt{P})_{,\theta}}{(r+ia\cos\theta)}\ .
\end{eqnarray}

A master equation for the gauge- and tetrad-invariant first-order massless perturbations of any spin in this background can be given starting from the following Newman-Penrose relations for any vacuum type D geometry (here considered with no backreaction) \cite{Teukolsky}
\begin{eqnarray}
\label{mia1}
&&
\{[D-\rho^{*}+\epsilon^*+\epsilon-2s(\rho +\epsilon)](\Delta+\mu-2 s \gamma)
\\
&&
  -[\delta+\pi^{*}-\alpha^{*}+\beta
-2 s(\tau+\beta)] \,(\delta^{*}+\pi-2 s\alpha)
  -2(s-1)(s-1/2)\psi_{2}\}\Psi=0
\nonumber
\end{eqnarray}
for spin weights $s=1/2,1,2$  and
\begin{eqnarray}\label{mia2}
&&
\{[\Delta-\gamma^{*}+\mu^{*}-\gamma-2 s (\gamma+\mu)](D-\rho-2s\epsilon)
\\
&&
-[\delta^{*}-\tau^{*}+\beta^{*}-\alpha
-2 s (\alpha+\pi)](\delta-\tau-2 s \beta)
-2(s+1)(s+1/2)\psi_{2}\}\Psi=0
\nonumber
\end{eqnarray}
for $s=-1/2,-1,-2$. The case $s=\pm 3/2$ can be derived instead  by following the work of
G\"uven \cite{guven}, which is expressed in the alternative Geroch-Held-Penrose formalism \cite{GHP}. Finally the case $s=0$ is given by
\begin{eqnarray}
\meqalign{
&[D\Delta+\Delta D-\delta^* \delta-\delta\delta^*
+(-\gamma-\gamma^*+\mu+\mu^*)D+(\epsilon+\epsilon^*-\rho^*-\rho)\Delta \cr
&+(-\beta^*-\pi+\alpha+\tau^*)\delta+(-\pi^*+\tau-\beta+\alpha^*)\delta^*]\Psi=0\ .
\cr}
\end{eqnarray}
Note that only in these NP equations has the standard notation for the directional derivatives
$D=l^\mu \partial_\mu$, $\Delta=n^\mu \partial_\mu$ and  $\delta=m^\mu \partial_\mu$ been used and the second of these should not be confused  with the equally standard notation for the metric quantity $\Delta= r^2-2{\mathcal M}r+a^2$ used everywhere else in this article.

As in the case of the Kerr spacetime \cite{bcjr} and the Taub-NUT spacetime \cite{TeukTN} all these equations for distinct spin weights can be cast into a single compact form in the
spinning C metric spacetime as well, by introducing a ``connection vector" with components
\begin{eqnarray}
&\Gamma^t =& \frac{\Omega^2}{\Sigma}\left\{\frac{1}{Q}\left[{\mathcal M}(A^2r^4+a^2)+r\sigma_0(\Delta -{\mathcal M}r)\right]\right.\nonumber \\
&&\left.+i\frac{a}{P}
\left[\sigma_0\cos\theta -A{\mathcal M}(1+\cos^2\theta)\right] \right\}\ ,
\nonumber\\
&\Gamma^r =& -\frac{\Omega}{\Sigma}\left( \frac12 \Omega Q_{,r}+2A\cos \theta Q\right)\ ,
\nonumber\\
&\Gamma^\theta =& \frac{2A\Omega  P r\sin \theta}{\Sigma} \ ,
\nonumber\\
&\Gamma^\phi =&-\frac{\Omega^2}{\Sigma}\left[\frac{aQ_{,r}}{2Q}+i\left( \frac{\cos\theta (2P-1)+A{\mathcal M}(\cos^2\theta -A^2a^2 \cos\theta +1)}{P\sin^2 \theta}\right)
\right]\ .
\label{eq:SPINNOL}
\end{eqnarray}
The resulting master equation has the form
\begin{equation}
[(\nabla^\mu+s\Gamma^\mu)(\nabla_\mu+s\Gamma_\mu)-4s^2\psi_2]\Psi=0\ ,\qquad
{\textstyle s=0,\pm\frac12,\pm1,\pm\frac32,\pm2}\ ,
\label{eq:bellak}
\end{equation}
where $\psi_2$ is the spinning C metric background Weyl scalar given by (\ref{psi2}).
This master equation characterizes the common behavior of all these massless fields in this background differing only in the value of the spin-weight parameter $s$. In fact, the first term on its left-hand side represents (formally) a wave (d'Alembert) operator, corrected by taking into account the spin-weight of the perturbing field, and the second term is a (Weyl) curvature term also linked to the spin-weight value.
Table \ref{TAB} shows the various Newman-Penrose quantities for which the master equation holds following the standard notation \cite{Teukolsky}, where in the spin-2 case $\psi_0$ and $\psi_4$ refer to the perturbed Weyl scalars.

\section{Separation of the master equation}

Remarkably the master equation (\ref{eq:bellak}) admits separable solutions of the form
\beq
\psi(t,r,\theta,\phi)=\Omega^{(1+2s)}e^{-i\omega t}e^{i m \phi} R(r)S(\theta)\ ,
\eeq
where $\omega>0$ is the wave frequency and $m$ is the azimuthal separation constant.
Note that as stated above the conical singularity along the symmetry axis is removed by insisting periodicity in the
azimuthal coordinate such that $\Delta\phi=\phi_0$.
Since $\phi$ is in this way a periodic coordinate, $m$ must be of the form $m=(2\pi/\phi_0)m_0=m_0\sigma_\pm$, with $m_0$ a positive integer, without loss of generality.

The radial equation is then
\beq
\label{radeq}
Q^{-s} \frac{\rmd}{\rmd r}\left(Q^{s+1}\frac{\rmd R(r)}{\rmd r} \right)
+V_{\rm (rad)}(r)R(r)=0\ ,
\eeq
with
\begin{eqnarray}
\label{radiale1}
V_{\rm (rad)}(r) &=&-2rA^2(r-{\mathcal M})(1+s)(1+2s)+\frac{\kappa(r)^2}{Q} \nonumber \\
&& -2is \left[
-\frac{amQ_{,r}}{2Q}+\frac{\omega {\mathcal M}(r^2-a^2)}{\Delta}-\frac{\omega r \sigma_0}{1-A^2r^2}
\right]+2K
\end{eqnarray}
where $K$ is the separation constant and the quantity
\beq
\kappa(r)=(r^2+a^2)\omega-am
\eeq
has been introduced following Teukolsky.
Clearly the solution $R(r)$ of this equation depends on the value of the spin weight $s$, so when convenient this dependence will be made explicit using the notation $R(r)\equiv R_s(r)$.
An analytic solution of this equation is expected only for very special values of $K$ (termed \lq\lq eigenvalues").
Algebraically special perturbations are considered in Section IV.
The existence of other closed form (or Liouvillian) solutions to this equation obtained by constraining black hole parameters, spacetime acceleration as well as separation constants is discussed in Appendix B.

Equation (\ref{radeq}) will be studied on the interval $r\in (r_+ , r_A )$, where the metric and the chosen tetrad (\ref{frame}) are well behaved, closely following the usual treatment of black hole perturbations that motivates the present investigation.

By introducing the scaling
\beq
R(r)=(r^2+a^2)^{-\frac 12}Q^{-\frac s2}H(r)\equiv \mathcal{Q}_s^{-1}\, H(r)
\eeq
and the ``tortoise" coordinate transformation $r\to r_*$, where
\begin{eqnarray}
\frac{\rmd r}{\rmd r_*}&=&\frac{Q}{r^2+a^2}\ ,\nonumber \\
r_*&=& \sigma_0\left[\frac{1}{A\sigma_+}\ln \sqrt{1+Ar} -
\frac{1}{A\sigma_-}\ln \sqrt{1-Ar}+\frac{{\mathcal M}}{\sigma_+\sigma_-}\ln \Delta
 \right]\nonumber \\
&& +\frac{2{\mathcal M}^2(1-a^2A^2)}{\sigma_+\sigma_- \sqrt{{\mathcal M}^2-a^2}}\ln \sqrt{\frac{r-r_+}{r-r_-}}+{\rm const}.\ ,
\end{eqnarray}
the radial equation can be transformed into the one-dimensional Schr\"odinger-like equation
\beq
\label{newradi}
\frac{\rmd ^2 }{\rmd r_*^2}H(r)+\tilde V H(r)=0\ ,
\eeq
with the potential
\begin{eqnarray}
\tilde V&=& \left[\frac{\kappa(r)}{r^2+a^2}-iG\right]^2-\frac{\rmd G}{\rmd r_*}
\nonumber \\
&&-\frac{2Q}{(r^2+a^2)^2}\left[rA^2 (r-{\mathcal M})(1+s)(1+2s)-K-2i\omega rs-\frac{ir\kappa(r) }{(r^2+a^2)}\right]\ ,
\end{eqnarray}
where
\beq
G=\frac{s[(r-{\mathcal M})(1-r^2A^2)-rA^2\Delta]}{(r^2+a^2)}+\frac{rQ}{(r^2+a^2)^2}
=\frac{\rmd}{\rmd r_*} \ln \mathcal{Q}_s
\eeq
has been introduced in analogy with Teukolsky's treatment of the perturbations of the exterior Kerr spacetime.

The asymptotic form of the radial equation as $r\to r_A \, (r_{*}\to\infty)$ is
\beq
\frac{\rmd ^2 }{\rmd r_*^2}H(r)+\left(\kappa_A-i\beta_A \right )^2 H(r)=0\ ,
\eeq
where
\beq
\beta_A=-\frac{As\sigma_-}{\sigma_0}\ , \qquad\kappa_A=\omega-m\omega_A\ , \qquad \omega_A=\frac{aA^2}{\sigma_0}\ .
\eeq
We notice that for small values of $A$ ($r_A \to \infty $) we approach the Teukolsky result:
\beq
\left(\kappa_A-i\beta_A \right )^2 \to \omega^2+ \frac{2is\omega}{r_A} +O(A^2)\ .
\eeq

On the other hand  close to the horizon $r\to r_+\, (r_{*}\to-\infty)$, the  asymptotic form of the radial equation becomes
\beq
\frac{\rmd ^2 }{\rmd r_*^2}H(r)+\left( \kappa_+ -i \beta_{+} \right )^2 H(r)=0\ ,
\eeq
where
\beq\label{omegahor}
\beta_{+}=\frac{s(r_+-{\mathcal M})(1-r_+^2A^2)}{2{\mathcal M} r_+}\ , \quad \kappa_+=\omega -m\omega_+\ , \quad \omega_+=\frac{a}{r_+^2+a^2}=\frac{a}{2{\mathcal M} r_+}\ ,
\eeq
with  $\omega_+$ the ``effective angular velocity" of the horizon.
Following Teukolsky, if $\frac{m\omega_+}{\omega}>1$ energy flows out from the hole, i.e. one has superradiant scattering.
Superradiance (see Ref. \cite{JAC} and references therein for an exaustive review) is a physical effect typically related  to rotation of totally absorbing objects.
More specifically, Zel'dovich \cite{zeldovich} in 1971 noticed that a cylinder made of absorbing material and rotating about its axis with frequency $\omega_+$ can amplify modes of scalar or electromagnetic radiation scattering on
it which satisfy the condition  $\omega-m\omega_+ < 0$, where $\omega$ is the  frequency of waves and $m$ the usual azimuthal quantum number.
In particular, in a curved spacetimes or in the effective curved geometries typical of acoustic black holes\cite{chersucci1}, the existence of an ergosphere allows one to extract rotational energy from the central engine, i.e. a field theory version of Penrose's process for point-like particles.
In presence of costant acceleration only (i.e. no rotation), superradiant effects are not expected.
On the contrary, in presence of rotation but not of constant acceleration, it is well known from Teukolsky's work that superradiant modes depend from the quantity $\omega_+$ previously computed.
It is natural to question now what happens in the more general case, which is the goal of our work:
in case of both acceleration $A$ and rotation $a$, related via the nonlinearities in Einstein's theory, the quantity  $\omega_+$ remains the same of Kerr solution, i.e. there is no coupling of acceleration and rotation in superradiant modes. This is a novel and a priori unxepected result of our analysis, and can have relevant implications for the understanding  both of complicated dynamics of moving rotating black holes in numerical relativity, as well as of experiments in ordinary fluids in the context of induced geometries.

To complete our analysis of the perturbations on the spinning C metric spacetime, we need to discuss the angular equation
\beq
\label{angolare}
\frac{1}{\sin\theta}\frac{\rmd }{\rmd \theta}
  \left(\sin\theta \frac{\rmd Y(\theta)}{\rmd \theta}\right)
  + V_{\rm (ang)}(\theta)Y(\theta)=0\ ,
\eeq
where
\begin{eqnarray}
\label{angolare1}
V_{\rm (ang)}(\theta)
&=&-\frac{2K-s(1-A^2a^2)}{P}+\frac{1}{P^2}\bigg\{
\frac{-\sigma_0^2s^2\cos^2\theta+2\sigma_0sw\cos\theta-w^2\cos^2\theta}{\sin^2\theta}\nonumber\\
&&+z^2\cos^2\theta-2s\sigma_0z\cos\theta-(z+w-4sA{\mathcal M})^2\nonumber\\
&&+A^2[({\mathcal M}^2-a^2)\sin^2\theta+4sa^2\cos\theta(2sA{\mathcal M}-w)]
\bigg\}\ ,
\end{eqnarray}
or equivalently:
\begin{eqnarray}
\label{angolare2}
V_{\rm (ang)}(\theta)
&=&\frac{1-2K+s(2-\sigma_0)}{P}+\frac{1}{P^2}\bigg\{
-\frac{(w\cos\theta-\sigma_0 s)^2}{\sin^2\theta}\nonumber\\
&&-(z+w-4s{\bar A})^2+(z\cos\theta-s\sigma_0)^2-({\bar A}\cos \theta -1)^2\nonumber\\
&&+1-\sigma_0+{\bar A}^2+4s(\sigma_0-1)\cos\theta(2s{\bar A}-w)
\bigg\}\ ,
\end{eqnarray}
where $Y(\theta)=\sqrt{P}S(\theta)$, $z=a\omega+s{\bar A}$ and $w=-m+2s{\bar A}$.
This equation generalizes the spin-weighted spheroidal harmonics of Teukolsky \cite{Teukolsky,FC,novello}.

In the limit of small values of the rotation parameter $a$ as well as acceleration parameter $A$, also neglecting terms of the order $aA$, the radial and angular potentials (\ref{radiale1}) and (\ref{angolare1}) reduce to
\begin{eqnarray}
V_{\rm (rad)}(r) &\simeq&\frac{\omega^2 r^3}{r-2{\mathcal M}} +2is\omega r
\frac{ r-3{\mathcal M}}{r-2{\mathcal M}}+2K -\frac{2ma}{r(r-2{\mathcal M})}[\omega r^2-is(r-{\mathcal M})]\ , \nonumber\\
V_{\rm (ang)}(\theta)&\simeq&\left[s-2K-\frac{(s\cos\theta+m)^2}{\sin^2\theta}\right](1+2{\bar A}\cos\theta)-2{\bar A}\left[sm-\frac{(s^2-m^2)\cos\theta}{\sin^2\theta}\right]\nonumber\\
&&+2\omega a (m-s\cos\theta)\ ,
\end{eqnarray}
respectively.
Note that the corrections due to $A$ to the radial potential  are $O(A^2)$ while those to the angular potential are $O(A)$.

We will discuss now the limiting cases of Kerr, Schwarzschild, C metric and Rindler spacetimes.

\subsection{Limiting cases}

\subsubsection{Kerr: $A=0$}

The radial equation (\ref{radeq}) reduces to
\beq
\label{radeqkerr}
\Delta^{-s} \frac{\rmd}{\rmd r}\left(\Delta^{s+1}\frac{\rmd R(r)}{\rmd r} \right)
+V_{\rm (rad)}^K(r)R(r)=0\ ,
\eeq
with
\begin{eqnarray}
V_{\rm (rad)}^K(r) &=&\frac{[-am +\omega(r^2+a^2)]^2}{\Delta} \nonumber \\
&& -2is \left[
-\frac{am\Delta_{,r}}{2\Delta}+\frac{\omega {\mathcal M}(r^2-a^2)}{\Delta}-\omega r\right]+2K
\end{eqnarray}
where $K$ is the separation constant.

The angular equation (\ref{angolare}) becomes
\beq
\frac{1}{\sin\theta}\frac{\rmd }{\rmd \theta}
  \left(\sin\theta \frac{\rmd Y(\theta)}{\rmd \theta}\right)
  + V_{\rm (ang)}^K(\theta)Y(\theta)=0\ ,
\eeq
where
\begin{eqnarray}
V_{\rm (ang)}^K(\theta)
&=&s-2K-
\frac{(s\cos\theta+m)^2}{\sin^2\theta}\nonumber\\

\frac{(s\cos\theta+m)^2}{\sin^2\theta}\nonumber\\
&&+(a\omega\cos\theta-s)^2
\ ,
\end{eqnarray}
where $Y(\theta)=S(\theta)$.

Following Teukolsky the separation constant in this case should be set as $K=[\Omega+s(s+1)-a\omega(a\omega-2m)]/2$, where $\Omega=-L(L+1)$.

\subsubsection{Schwarzschild: $A=0$, $a=0$}

+V_{\rm (rad)}^S(r)R(r)=0\ ,
\eeq
with
\begin{eqnarray}
V_{\rm (rad)}^S(r) &=&\frac{\omega^2 r^3}{r-2{\mathcal M}} +2is\omega r

&=&s-2K-
\frac{s^2\cos^2\theta+2sm\cos\theta+m^2}{\sin^2\theta}\ ,
\end{eqnarray}
where $Y(\theta)=S(\theta)$.

The separation constant in this case should be set as $K=[\Omega+s(s+1)]/2$, where $\Omega=-L(L+1)$.

\subsubsection{C metric: $a=0$}

The radial equation (\ref{radeq}) reduces to
\begin{eqnarray}
\label{radeqcmet}
&&[(1-A^2r^2)(r^2-2{\mathcal M}r)]^{-s} \frac{\rmd}{\rmd r}\left([(1-A^2r^2)(r^2-2{\mathcal M}r)]^{s+1}\frac{\rmd R(r)}{\rmd r} \right)\nonumber\\
&&+V_{\rm (rad)}^C(r)R(r)=0\ ,
\end{eqnarray}
with
\begin{eqnarray}
V_{\rm (rad)}^C(r) &=&-2rA^2(r-{\mathcal M})(1+s)(1+2s)+\frac{\omega^2r^4}{1-A^2r^2} \nonumber \\
&& -2is\omega r \left(
\frac{{\mathcal M}}{r-2{\mathcal M}}-\frac{1}{1-A^2r^2}
\right)+2K
\end{eqnarray}
where $K$ is the separation constant.

The angular equation (\ref{angolare}) becomes
\beq
\frac{1}{\sin\theta}\frac{\rmd }{\rmd \theta}
  \left(\sin\theta \frac{\rmd Y(\theta)}{\rmd \theta}\right)
  + V_{\rm (ang)}^C(\theta)Y(\theta)=0\ ,
\eeq
where
\begin{eqnarray}
V_{\rm (ang)}^C(\theta)
&=&-\frac{2K-s}{P_C}+\frac{1}{P_C^2}\bigg\{
\frac{-s^2\cos^2\theta+2sw\cos\theta-w^2\cos^2\theta}{\sin^2\theta}\nonumber\\
&&+z^2\cos^2\theta-2sz\cos\theta-(m+s{\bar A})^2+{\bar A}^2\sin^2\theta
\bigg\}\ ,
\end{eqnarray}
where $Y(\theta)=\sqrt{P_C}S(\theta)$, $P_C=1-2{\bar A}\cos\theta$, $z=s{\bar A}$ and $w=-m+2s{\bar A}$.

\subsubsection{Rindler: $M=0=a$}

The radial equation (\ref{radeq}) reduces to
\beq
\label{radeqrind}
(1-A^2r^2)^{-s} \frac{\rmd}{\rmd r}\left((1-A^2r^2)^{s+1}\frac{\rmd R(r)}{\rmd r} \right)
+V_{\rm (rad)}^R(r)R(r)=0\ ,
\eeq
with
\begin{eqnarray}
V_{\rm (rad)}^R(r) &=&-2r^2A^2(1+s)(1+2s)+\frac{\omega r(\omega r^3+2is)}{1-A^2r^2}+2K
\end{eqnarray}
where $K$ is the separation constant.

The angular equation (\ref{angolare}) becomes
\beq
\frac{1}{\sin\theta}\frac{\rmd }{\rmd \theta}
  \left(\sin\theta \frac{\rmd Y(\theta)}{\rmd \theta}\right)
  + V_{\rm (ang)}^R(\theta)Y(\theta)=0\ ,
\eeq
where
\begin{eqnarray}
V_{\rm (ang)}^R(\theta)
&=&s-2K-\frac{s^2\cos^2\theta+2sm\cos\theta+m^2}{\sin^2\theta}\ ,
\end{eqnarray}
where $Y(\theta)=S(\theta)$.

\section{Algebraically special perturbations}

Consider the radial equation (\ref{radeq}). In analogy with the Schwarzschild black hole case one can find analytic solutions of this equation for $s=+2$ given by
\beq
R(r)=\frac{c_3r^3+c_2r^2+c_1r+c_0}{Q^2}e^{-i\omega \tilde r}, \qquad \tilde r= \int \frac{r^2+a^2-\frac{am}{\omega}}{Q} \, \rmd r\ .
\eeq
Substituting into Eq. (\ref{radeq}) one obtains a 7$^{th}$ degree polynomial equation in $r$ which must be identically zero, i.e. the coefficient of any power of $r$ should vanish leading to a homogeneous linear system of $8$ equations in the $4$ variables
$c_0, \ldots c_3$ (consequence of the fact that the coefficient of any power of $r$ is a linear function of  $c_0, \ldots c_3$).
This system is compatible assuming the following constraint (generalizing the Starobinsky constraint):
\beq
P_2(x)+P_4(y)+P_2^q(y)+C=0\ ,
\eeq
where $x={\mathcal M}\omega$, $y=a\omega$, $q={\bar a}{\bar A}$ and
\begin{eqnarray}
P_2(x)&=&9x^2 \nonumber \\
P_4(y)&=&9y^2(y-m)^2-2y(K-2)[(5K-7)y -(5K-13)m] \nonumber \\
P_2^q(y)&=& 9(y-m)^2q^2\bar A^2-(28q^2-74+34K)q^2y^2+2q^2my (2q^2+11K-37).
\end{eqnarray}
We have
\begin{eqnarray}
C&=& [(K-2)(K-3)-3{\bar A}^2+q^2(5K-9+6q^2)]^2\nonumber\\
&&+3m^2q^2(8q^2+4K-8)\nonumber \\
&\equiv & W^2 +12m^2q^2[K-2(1-q^2)] \ .
\end{eqnarray}

The solution is implicitly given by
\begin{eqnarray}
\frac{c_0}{{\mathcal M}^4}&=& \frac{c_1}{ {\mathcal M}^3} \frac{[i\bar a(y-m)-1]}{K-2(1-q^2)}-\frac{c_2}{ {\mathcal M}^2} \frac{\bar a^2}{K-2(1-q^2)}\nonumber \\
\frac{c_3}{{\mathcal M}}&=& \frac{c_1}{{\mathcal M}^3} \frac{\bar A^2}{K-2(1-q^2)}+\frac{c_2}{{\mathcal M}^2} \frac{\bar A^2-x}{K-2(1-q^2)}
\end{eqnarray}
with $c_1$ arbitrary and $c_2$ given by
\begin{eqnarray}
\frac{c_2}{{\mathcal M}^2}&=&2i\frac{c_1}{ {\mathcal M}^3}\frac{[(K-2-q^2)x+3q\bar Am]}{\left\{
-W^2+3y(y-m)+3i[x(q^2-1)+q\bar Am]\right\}}\ .
\end{eqnarray}

The limiting cases of Kerr, Schwarzschild, C metric and Rindler spacetimes are discussed below.

\eeq
Substituting into Eq. (\ref{radeqkerr}) one obtains a 5$^{th}$ degree polynomial equation in $r$ which must be identically zero.
This system is compatible assuming the following constraint:
\beq
P_2(x)+P_4(y)+
C=0\ ,
\eeq
where $x={\mathcal M}\omega$, $y=a\omega$ and

\end{eqnarray}
with $c_1$ arbitrary and $c_2$ given by
\begin{eqnarray}

W^2+3ix}\ .
\end{eqnarray}

\subsubsection{C metric: $a=0$}

Consider the radial equation (\ref{radeqcmet}). One can find analytic solutions of this equation for $s=+2$ given by
\beq

\eeq
Substituting into Eq. (\ref{radeqcmet}) one obtains a 6$^{th}$ degree polynomial equation in $r$ which must be identically zero.
This system is compatible assuming the following constraint:
\beq
P_2(x)+C=0\ ,
\eeq
where $x={\mathcal M}\omega$ and

\end{eqnarray}
We have
\begin{eqnarray}
C&=& [(K-2)(K-3)-3{\bar A}^2]^2\equiv  W^2 \ .
\end{eqnarray}

The solution is implicitly given by
\begin{eqnarray}
\frac{c_0}{{\mathcal M}^4}&=&- \frac{c_1}{ {\mathcal M}^3} \frac{1}{K-2}\nonumber \\
\frac{c_3}{{\mathcal M}}&=& \frac{c_1}{{\mathcal M}^3} \frac{\bar A^2}{K-2}+\frac{c_2}{{\mathcal M}^2} \frac{\bar A^2-x}{K-2}

\subsubsection{Rindler: ${\mathcal M}=0$, $a=0$}

Consider the radial equation (\ref{radeqrind}). One can look for analytic solutions of this equation for $s=+2$ given by

Substituting into Eq. (\ref{radeqrind}) one obtains a 5$^{th}$ degree polynomial equation in $r$ which must be identically zero.
This system admits only the trivial solution $c_3=c_2=c_1=c_0=0$ and therefore in this case there exists no algebraically special solutions.

\section{Concluding remarks}

A master equation for the gauge- and tetrad-invariant first-order massless perturbations of any spin $s\leq2$ on the spinning C metric background spacetime has been obtained and separated.
We have studied superradiance in this case and have shown that the situation is very similar to the Kerr spacetime; in particular, we have demonstrated that there is no coupling of spacetime acceleration and rotation in superradiant modes.
This investigation offers the possibility of achieving a better understanding of perturbations of black hole spacetimes within this larger family; moreover, our work may be relevant to string theory, where the spinning C metric spacetime is of interest for other reasons.

TransPerfect leaves Delaware as corporate home, citing Chancery Court dispute

Following a lengthy court battle over the court-ordered sale of the company, the multimillion-dollar language services TransPerfect has relocated its corporate home from Delaware to Nevada.
For more than three years, TransPerfect co-founder Phil Shawe fought against a Delaware Chancery Court order to auction off the company following a dispute with his former fiancée, Elizabeth Elting. Like thousands of other companies — including a majority of the Fortune 500 — TransPerfect was incorporated in Delaware, in part to take advantage of the state's Chancery Court and its vast experience in handling business disputes. That led Elting to ask the Delaware court to appoint a custodian to break up the company to settle her dispute with Shawe.
Shawe launched a highly visible public relations campaign to prevent the sale of the company, and he called on Delaware lawmakers to change state law to stop it. Despite several rallies with TransPerfect workers at Legislative Hall in Dover, the lobbying efforts did not succeed.
In May, the Delaware Supreme Court approved the Chancery Court order to auction off the company. Shawe won the auction with a bid of $770 million.
Unhappy with the court's handling of the case, Shawe announced this week that TransPerfect has changed its corporate home to Nevada, encouraging other companies to consider doing the same.
"For many years, most companies, including ours, considered Delaware the default option for incorporation. But times and circumstances have changed. Other states, Nevada chief among them, now represent compelling alternatives," Shawe said in a statement.
The statement goes on to blame Chancery Court's handling of the TransPerfect case for Delaware's lower ranking in the U.S. Chamber of Commerce business litigation survey. In 2015, the state had been ranked first, but the 2017 survey puts Delaware at 11th.

Thousands of war crime charges against British soldiers during Iraq war dropped
By Froilan Malit on June 4, 2020 Asia News, News
Thousands of war crime accusations tabled against British soldiers in Iraq have been dismissed, with only one case remaining to be resolved, the director of the Service Prosecution Authority (SPA) has said.
Human rights groups and some lawyers have expressed concern, saying the legislation could place the military above the law and undermine existing international conventions.
SPA Director Andrew Cayley said the "low level" of offending and lack of credible evidence had led most cases to be dismissed.
Speaking to BBC Radio 4's Law in Action programme, Mr. Cayley said most of those cases were sifted out at a very early stage because of the lack of credible evidence or because the offence was "at such a very low level".
More than 1,000 cases were made by former lawyer Phil Shiner and his firm Public Interest Lawyers (PIL). In 2017 he was struck off as a solicitor after a tribunal found him guilty of misconduct and dishonesty, including false accounts about the actions of UK soldiers.
Mr. Cayley said seven remaining cases had been referred to the SPA, but in six of those cases it was concluded that no charges should be brought.
One case is still being considered, but Mr. Cayley admitted that it is now "quite possible" that none of the original allegations will lead to a prosecution.
Mr. Cayley also said he is confident a separate investigation being conducted by the International Criminal Court (ICC) in the Hague will conclude this year without further action being taken.
In 2014, ICC prosecutor Fatou Bensouda re-opened a preliminary examination of cases involving alleged British abuses in Iraq.
Mr. Cayley said he was "convinced" that examination would soon be completed without any further action, adding "my sense is these matters are coming to a conclusion; she will close the preliminary examination this year in respect of Iraq and the United Kingdom."
The cloud hanging over British service personnel accused of wrongdoing has already left a bitter taste and contributed to political pressure to do more to protect soldiers on the battlefield from criminal and civil prosecution for alleged actions which took place years ago.
Earlier this year the government presented a bill promising to curb historic allegations and tackle what it calls "vexatious claims" against armed forces deployed overseas.
The bill proposes a five-year time limit on any criminal prosecution unless compelling new evidence is brought to light.
In a statement, the Ministry of Defence said it was strongly opposed to service personnel and veterans being subjected to the threat of repeated investigations and potential prosecutions.
Veterans minister Johnny Mercer said the bill was introduced "to reduce the uncertainty currently faced by service personnel and veterans in relation to historic allegations" – and aimed to make sure "that we never end up in a situation like this again". (Source: BBC)

December isn't the best time to visit Minnesota, but I'll give the geography this kudo: it's flat. And for some reason they make a good buffalo wing out there, even though it's across the lakes from Buffalo, NY. Many miles away.
I was out there last week with [[UnnamedCustomerWhoWillNotBeNamed]], supporting some Lab work to help customer plan a heterogenous data migration from a few different storage platforms through HDS VSP.
We spent a day-and-a-half pushing the envelope (which is generally known as "Doing Technology the Wrong Way;" but that's what labs are for), and the rest of the time documenting the right way to ingest LUNs through the HDS VSP back-door and out through the front.
Sidenote: if you'd like to join the party, please do so – request an event in Datalink labs.
Customer went home on Friday indicating they had a pleasant and instructive time.
I learned much thanks to my peers facilitating the process: Sorbs, Wibstad, Newhouse and Sonderegger, and I look forward to seeing them at the Datalink Summit in a few weeks, where I can thank them properly.
 Nor are November, January, February, March and sometimes April, May and October; it's frozen, and when it's not frozen it's merely cold and wet.
