Gravitational Wave S6 Directed Search (CasA) ending
We are nearing the end of the "S66CasA GW run". This means that only relatively few tasks of possibly remote frequency bands are available for this application, possibly resulting in an increased download volume per task. If you want to avoid this, you may opt-out of the "Gravitational Wave S6 Directed Search (CasA)" search in your Einstein@Home preferences on the web site.

Gravitational Wave search GPU App version
Due to the excellent work of our French volunteer Christophe Choquet we finally have a working OpenCL version of the Gravitational Wave search ("S6CasA") application. Thank you Christophe!

This App version is currently considered 'Beta' and being tested on Einstein@Home. To participate in the Beta test, you need to edit your Einstein@Home preferences, and set "Run beta/test application versions?" to "yes".

It is currently available for Windows (32 Bit) and Linux (64 Bit) only, and you should have a card which supports double precision FP in hardware.

Syracuse University moves into first place!
Congratulations to Syracuse University, which has passed the AEI E-Science Group to move into FIRST PLACE among Einstein@Home contributors. Syracuse University has now contributed more computer cycles to the Einstein@Home search than any other participant. Thank you Syracuse!!

Einstein@Home Volunteers Discover Four "Young" Gamma-Ray Pulsars
Congratulations to our volunteers:

Thomas M. Jackson, Kentucky, USA
Mak-ino, Japan
Doug Lean, Australia
Hans-Peter Tobler, Germany
NEMO computing cluster, UW-Milwaukee, USA
Chen, USA
David Z, Canada
Test, France

whose computers have found 4 new gamma-ray pulsars in data from the Large Area Telescope on board NASA's Fermi Satellite. These are the first gamma-ray pulsars ever discovered by Einstein@Home; only a few dozen such objects (spinning neutron stars whose pulsations are only visible via their gamma rays) are known.

The scientific paper is available here (use PDF link on the top right-hand side) and will be published in the next hours in the Astrophysical Journal Letters. If you are interested in learning more, a press release and other materials concerning the discovery are also available on-line.

Many thanks to all Einstein@Home volunteers, whose computers have made these exciting discoveries possible!

New radio pulsar discovered in Arecibo data
Congratulations to our volunteers James Drews, UW-Madison and juergenstoetzel. Their computers have discovered a new radio pulsar J1859+03, in data from the Arecibo Observatory PALFA survey.

Drews works at the University of Wisconsin, Madison, and is the ninth-ranked Einstein@Home volunteer, measured by total computing credits. This is his second pulsar discovery!

Further details about these and other Einstein@Home pulsar discoveries can be found on this web page, and will be published in due course.
