Einstein@Home Radio Pulsar Search Paper Published

A detailed paper about the Einstein@Home search for radio pulsars and first discovery has been published in the Astrophysical Journal. This will be available free of charge starting in one year. Until then, a copy of the manuscript may be obtained from the Cornell University Library arXiv Server: use the the "Download: PDF" link on the top right of the page.

Einstein@Home Radio Pulsar Search Paper Published

Plenty of reading, thanks Bruce

I better switch over to a desktop before my battery goes dead and the laptop thinks it doesn't have to work here.

Hallo!
Thanks for your information.
I donwnloaded it and had a very short look through. Later I will read it in more detail.
Thanks for naming our effort.

Kind regards and happy crunching

Thanks for the paper, btw ;)

Google translates this to "As a Chinese person in my country think boinc is useless to hope that you will spread"

Yeah I tried another translator and got the same thing.

I would say that post was useless and hope that it gets deleted (my own translation)

Hmmmm. I'd try : I am Chinese, it is useless to hope that boinc will spread in my country.

In any case, well done to all involved at E@H with the publication of this work. It's a great encapsulated description of the project.

Raise glasses, group hug and high fives all around ! :-) :-)

Cheers, Mike.

( edit ) I always boggle a bit with the numbers you get from astrophysics. Take " ... orbital periods as short as 11 minutes ... ". Try to imagine being nearby two multi-solar mass objects swirling close in to each other to achieve this rate. Close quarters battle or what ? Then there's " ... 40.8 Hz isolated pulsar ... ", being another multi-solar mass object rotating as fast as the engine's crankshaft in my car when I'm just tooling along the road @ ~ 2400 RPM. Plus " ... age of 404 Myr ... " ie. even before the dinosaurs.

Neither, this paper refers to the pulsar searches via electromagnetic radiation.

Cheers, Mike.

As a Chinese I can't understand such an incorrect and ambiguous sentence.

Here is a long answer to a simple question!

(1) The paper is NOT about gravitational waves; it's about finding spinning neutron stars via their radio emissions.

(2) Gravitational waves have never been directly observed. Einstein@Home will continue to search for gravitational waves from spinning neutron stars.

(3) Gravitational waves HAVE been found (indirectly). For example in the binary system PSR 1913+16 (discovered by Hulse and Taylor more than thirty years ago) the emission of gravitational waves causes the orbit to shrink a few millimeters every ~8 hours. This loss of energy is exactly what would be caused by gravitational wave emission at twice the orbital period.

Cheers,
Bruce
