With Fermi leading the way, we now know where to concentrate our search efforts for millisecond pulsars," said Jason Hessels, an ASTRON Staff Astronomer who recently discovered four of the new batch of millisecond pulsars using ASTRON's "DROP" computer cluster to perform the required heavy calculations.
Markwardt and Jean Swank of Goddard identified the source as material falling onto a millisecond pulsar from its companion.
The real surprise is that 47 Tuc seems to contain only two or three quiescent low-mass X-ray binaries, the presumed progenitors of millisecond pulsars.
Precise monitoring of timing changes in an all-sky array of millisecond pulsars may allow the first direct detection of gravitational waves - a long-sought consequence of Einstein's relativity theory.
These capabilities, which are strongly linked to GuideTech's unique CTIA technology, enable critical, high-speed, functional, timing and jitter test coverage for PLLs and multi-gigabit serial interfaces such as PCI Express and Serial ATA, in milliseconds, in parallel, and in production.
Because a millisecond pulsar is elderly and most likely formed planets much later in life than the infant sun, its planets probably contain far more iron and other heavy elements typical of older stars, he says.
But according to several researchers, this recipe for "born-again" millisecond pulsars may have a fatal flaw.
Supporting a high brightness of 300 cd/m2 and 2 millisecond response rates, the AL1951D also supports a contrast ratio of 1000:1 for brilliant colors and photo-like image quality
Sending out bursts of radio waves up to 600 times a second, millisecond pulsars have intrigued astronomers since a discovery four years ago that some reside at the heart of dense amalgams of Milky Way stars.
Finding a millisecond pulsar -- a rapidly spinning neutron star -- is about as difficult as locating the proverbial needle in a celestial haystack.
Initially, everybody thought that in globular clusters we would find predominantly rapidly spinning, millisecond pulsars," Wolszczan says.
8 NATURE, David Eichler of Ben-Gurion University in Beer Sheva, Israel, suggests looking in the vicinity of isolated millisecond pulsars for traces of dark matter--invisible material, detectable only through its gravitational influence, that could make up as much as 90 percent of the mass in the universe.
