Astronomers report the finding of a new candidate redback millisecond pulsar (MSP) binary associated with a gamma-ray source known as 4FGL J0940.3–7610. The newly found object is a short-period compact binary exhibiting ...
Using NASA's Chandra spacecraft, astronomers have inspected X-ray emission from the center of a young radio galaxy known as NGC 3894. Results of this study, presented in a paper published June 24 on the arXiv pre-print server, ...
The SLAC-built Large Area Telescope (LAT), the main instrument of the Fermi Gamma-ray Space Telescope, has been studying the gamma-ray sky for almost four years. During that time, the LAT has identified hundreds of gamma-ray ...

(PhysOrg.com) -- Physicist Nathan Whitehorn and a team of researchers with the IceCube collaboration have failed to come up with evidence to prove that neutrinos come from, or are caused by, gamma ray bursts, (cosmic explosions) ...
Supernovae, neutron star collisions and active galactic nuclei are among the most energetic phenomena in the known universe. These violent explosions produce high-energy gamma rays and cosmic rays, which can easily travel ...
