Actually, the group of bananas commonly referred to as a bunch at the store is actually a hand, or less commonly tier.
PSR B1509-58 - X-rays from Chandra are gold; Infrared from WISE in red, green and blue/max. A pulsar (from pulse and -ar as in quasar) is a highly magnetized, rotating neutron star or white dwarf, that emits a beam of electromagnetic radiation. This radiation can be observed only when the beam of emission is pointing toward Earth (much like the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission.
Our PulsâarÂ® XP ALD reactor helped to enable the switch to hafnium-based high-k dielectrics for transistor gates. Pulsar has been used in volume production for high-k gates since 2007 at the 45nm node and is now in production running 28nm generations. In cooperation with our customers and R&D partners, Pulsar is being used to achieve the performance requirements of 20nm and beyond transistor gates.
