The U.S. Naval Research Laboratory and the Fermi Large Area Telescope Collaboration have discovered nearly 300 gamma ray pulsars, advancing pulsar research and contributing to gravitational wave studies and navigation applications. The findings also include insights into “spider” pulsars, where a neutron star interacts intensively with its binary companion.
The U.S. Naval Research Laboratory (NRL), in conjunction with the international Fermi Large Area Telescope Collaboration, has announced the discovery of almost 300 gamma ray pulsars. This announcement was made in their Third Catalog of Gamma Ray Pulsars, marking a significant achievement 15 years after the 2008 launch of the Fermi telescope. At the time of Fermi’s launch, there were less than ten known gamma-ray pulsars.
“Work on this important catalog has been going on in our group for years,” said Paul Ray, Ph.D., head of the High Energy Astrophysics and Applications Section at NRL. “Our scientists and postdocs have been able to both discover and analyze the timing behavior and spectra of many of these newfound pulsars as part of our quest to further our understanding of these exotic stars that we are able to use as cosmic clocks.”
