EINSTEIN@HOME Discoveries Blossom in the Parkes Multi Beam Pulsar Survey (PMPS)
20 August, 2011 06:31 CST6CDTOn August 19th, 2011, three new radio pulsars discoveries were announced in the Parkes data by users donating computer time for the Boinc Einstein@Home project. About one month earlier, July 26th, 2011 a sixth discovery was detected. This brings the total pulsar discoveries to the count of nine from Einstein@Home community contributions.
So far, the Einstein@Home-PMsurv re-analysis has found nine new pulsars, which were confirmed with recent observations. - [E@H-PMsurv discoveries]
"The Parkes multibeam pulsar survey uses a 13-element receiver operating at a wavelength of 20 cm to survey the inner Galactic plane with remarkable sensitivity." - astro-ph/9911185 ; CAL-FC-1110
Rotating radio transients (RRATs) are sources of short, bright, radio pulses, which were first discovered in 2006.[1] The pulses emitted by RRATs are similar to those observed from pulsars, but the characteristic regularity of pulsars is absent from RRATs. Like pulsars, RRATs are thought to be associated with rotating magnetized neutron stars, but the cause of their irregularity is unknown. - [Read More @ WikipediA]

EINSTEIN@HOME Crunches on the Fermi Paradox
11 July, 2011 18:43 CST6CDTAnnouncement
We are launching a new Einstein@Home application, which searches data from the Fermi Large Area Telescope (Fermi-LAT) for millisecond (or slower) gamma-ray pulsars. The Fermi Satellite was launched in mid-2008 and has already discovered a number of new gamma-ray pulsars. Questions, comments and problem reports about the new search and application should be placed onto this message board thread. Bruce Allen Director, Einstein@Home - [source]
Fermi Large Area Telescope
The Large Area Telescope (LAT) is the principal scientific instrument on the Fermi Gamma Ray Space Telescope spacecraft. Originally called the Gamma-Ray Large Area Space Telescope (GLAST), the mission was renamed for the physicist Enrico Fermi. The Fermi spacecraft was launched into a near-earth orbit on 11 June 2008. The design life of the mission is 5 years and the goal for mission operations is 10 years. The Fermi LAT instrument collaboration is an international effort, funded by agencies in several countries[*].
The LAT is an imaging high-energy gamma-ray telescope covering the energy range from about 20 MeV to more than 300 GeV. Such gamma rays are emitted only in the most extreme conditions, by particles moving very nearly at the speed of light. The LAT's field of view covers about 20% of the sky at any time, and it scans continuously, covering the whole sky every three hours. - [source]
Fermi's paradox
The Fermi paradox (Fermi's paradox or Fermi-paradox) is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilizations and the lack of evidence for, or contact with, such civilizations.
The age of the universe and its vast number of stars suggest that if the Earth is typical, extraterrestrial life should be common.[1] In an informal discussion in 1950, the physicist Enrico Fermi questioned why, if a multitude of advanced extraterrestrial civilizations exists in the Milky Way galaxy, evidence such asspacecraft or probes is not seen. A more detailed examination of the implications of the topic began with a paper by Michael H. Hart in 1975, and it is sometimes referred to as the Fermi–Hart paradox.[2] Other common names for the same phenomenon are Fermi's question ("Where are they?"), the Fermi Problem, the Great Silence,[3][4][5][6][7] and silentium universi[7][8] (Latin for "the silence of the universe"; the misspelling silencium universi is also common).
There have been attempts to resolve the Fermi paradox by locating evidence of extraterrestrial civilizations, along with proposals that such life could exist without human knowledge. Counterarguments suggest that intelligent extraterrestrial life does not exist or occurs so rarely or briefly that humans will never make contact with it.

For those of you wondering what the EINSTEIN@HOME Project is:
Einstein@Home uses your computer's idle time to search for weak astrophysical signals from spinning neutron stars (also called pulsars) using data from the LIGO gravitational-wave detectors, the Arecibo radio telescope, and the Fermi gamma-ray satellite. Einstein@Home volunteers have already discovered more than a dozen new neutron stars, and we hope to find many more in the future. Our long-term goal is to make the first direct detections of gravitational-wave emission from spinning neutron stars. Gravitational waves were predicted by Albert Einstein almost a century ago, but have never been directly detected. Such observations would open up a new window on the universe, and usher in a new era in astronomy.My name is Andy Wright - the founder, but really the creator of Team FreeBSD. If you want me to add any links, or have any questions or inclinations for such things related to our group (or to just say hi) - send me an e-mail: einstein@extracted.org or Skype name: extracted

| Einstein@Home volunteers discover three new radio pulsars in Arecibo data |
Einstein@Home volunteers have discovered three new radio pulsars in Arecibo PALFA data -- the eighth, ninth and tenth new radio pulsars found by Einstein@Home volunteers in this data set! Congratulations to:
Further details about these newly-discovered pulsars can be found on this web page, and will be published in due course.
