We are delighted to announce that Einstein@Home has made its first discovery: a radio pulsar, found in data from the Arecibo Observatory in Puerto Rico.

Details are available in a paper published online by Science today. Science has given us permission to post a copy of the abstract and paper here. They are also on the Science website here. The manuscript is also in the arXiv preprint archive (use the PDF link in the top right corner).

A press-conference webcast about this first discovery is also available.

The name of the pulsar is PSR J2007+2722. It is a 40.8 Hz isolated pulsar, 17,000 light years distant in the plane of the Galaxy, and is most likely a Disrupted Recycled Pulsar (DRP). If so, it is the fastest DRP yet discovered.

The Einstein@Home volunteers whose computers found the pulsar with the highest significance are Chris and Helen Colvin, from Ames Iowa and Daniel Gebhardt, Musikinformatik, Universitaet Mainz.

Additional information about the discovery is available on our web pages. I will also talk about it at the London Citizen Cyberscience Summit on September 2nd.

We thank ALL Einstein@Home volunteers for their support, and look forward eagerly to our next discovery.

Bruce Allen, Director, Einstein@Home

Wow, this is big news. Congratulations to everybody who made this possible. And Helen, Chris and Daniel, I am soooooo jealous!

Then the method is sound. Was it ABP2?

Congratulations!

I believe in Einstein@Home since February of 2005 and believe that is only first discovery of this project!

Congratulations with this discovery!

Goes to show we're not doing this for nothing (or credits only). :-)

Congratulations to the volunteers and the AEI staff involved in this discovery! I think this is a great day also for BOINC in general and the concept of citizen science.

Cheers

My heart skipped a beat or three !! This awesome .... :-) :-)

As Homer Simpson says : "it works on so many levels". It is indeed a multiple first and is a boon to the entire DC community. [ Having said that I am ever so cheesy grin that it was E@H - but that's my personal bias :-) ].

Looking at the detail, the discovery is at least mild on the weirdo scale - not in the middle of the pulsar garden - and I will eagerly await further definition of this beastie ....

[ I think I see harmonics ( of ~ 40Hz ) on the plot, more or less of equal strength and a suggestion of sidebands. I'm going to stare at the animations for a while ... ]

Cheers, Mike.

( edit ) Ah I can imagine, I reckon, the annular/crater like morphology of the emission cone, with our line-of-sight trekking across the outer edge, dipping in, running across the crater floor ( not hitting the exact centre but not far off it either ) and then slipping up and over the other side ( with a mild asymmetry between the outer rim slopes on entry and exit ). The pulse profile is the equivalent of a surveyors elevation map along a traverse line/cut - likely not an actual physical feature of the pulsar surface but in the sense of variation in emission strength with surface position. The edge of the glowing yellow cone in the animation is the peak of the 'crater rim'.

As a long-time fan of this project, I am excited to hear the excellent news! The sneak announcement of a possible second pulsar discovery (see time 22:00 to 22:35 in the NSF webcast) means the race is on. Congratulations to the lucky discoverers and let's keep crunching....

Yes I saw that, contributors from UK and Russia putatively. I also thought that this announcement may trigger a spot of gold-rush fever ..... there's pulsars in them thar hills! :-)

Cheers, Mike.

( edit ) I think the E@H PALFA/ABP WU fraction ( of total distributed ) is going to increase too ???

( edit ) From here

“This is the first time I’ve worked closely with radio astronomers making a discovery,” said Allen. “It was like watching 5-year-olds tearing Christmas presents. Or like watching someone throw chunks of meat at starving sharks.”

So maybe any gold rush will influx from both sides : computing contributors and those that seek to harness .... thus with more ( catalytic ) power to both.

You know you've hit the big time when you are the featured story on the Coast To Coast AM Radio Show web site!

Congratulations!!

edit: I'm fairly certain that George Noory will make mention of it on tonights show which starts at 22:00 PDT. C2C has a huge audience, well, coast to coast, and globally via the Internet and satellite radio.

From the BBC also. This coverage will do distributed computing some good.

At the time of writing this, the article is second on the sites list of "Most popular" articles. Of course, early at the moment in the UK.

I'm disappointed at the rate with which new volunteers are joining Einstein@Home. My hope was that the publicity would get us 1000 new volunteers per hour, for a week. The current rate is about 150 per hour.

Could anyone suggest what might be done to improve this, in the next days? One suggestion was, if you read an on-line article about E@H, please add something to the 'COMMENT' area below the article, saying "to sign up, point your web browser to http://einstein.phys.uwm.edu/ and follow the instructions: Join Einstein@Home".

This is a good idea!


Maybe we can add also "if you are already signed up but your RAC is <10... no chance for you to discover a new pulsar :-D"

P.S. congratulations !!!!!

What about contributors directly contacting one's local media outlets with a suggestion ( eg. provide E@H website link ) to follow-up/research the story, evidently in the science category. One couldn't/wouldn't have to speak on behalf of E@H, but simply give them a heads up on the discovery. Our national broadcaster ABC and most of the DownUnda major networks et al have some variety of online contact from the general public to their newsrooms available ( email, web form etc .. ). This could be virally effective.

Cheers, Mike.
