News about Einstein@Home searches for radio and gamma-ray pulsars

Dear Einstein@Home volunteers,
We'd like to update you about our searches for new neutron stars using data from radio telescopes and from the Fermi gamma-ray satellite. Thanks to you, Einstein@Home has already found 55 new radio pulsars and 39 new gamma-ray pulsars. With your continued support, we believe that many more will follow.

Results from deep all-sky search on LIGO O3 data
The results of our all-sky search for continuous gravitational waves in public data from LIGO's third observing run (O3) have been published on the arXiv preprint server: Deep Einstein@Home all-sky search for continuous gravitational waves in LIGO O3 public data. The manuscript is currently in the peer-review process for publication in The Astrophysical Journal.

...The search did not reveal any gravitational-wave signal. Based on this we draw conclusions about the population of neutron stars in our Galactic neighborhood. For example, within 100 parsecs (~330 light-years) around Earth there are no neutron stars rotating faster than 12,000 rpm with equatorial mountains larger than half a millimeter; otherwise we would have very likely detected their continuous gravitational waves.

"...there are no neutron stars rotating faster than 12,000 rpm with equatorial mountains larger than half a millimeter..." Wow the level of precision is astonishing.
