A pair of astrophysicists at Universidad Nacional Autonoma de Mexico has found, via study of data from the low-Earth orbiting Fermi Gamma-ray Space Telescope, regular gamma radiation pulses emanating from around the black ...
Astronomers with The LHAASO Collaboration have found that last year's GRB 221009A gamma-ray burst, subsequently nicknamed the Brightest of All Time (BOAT), carried with it 13 teraelectronvolts of energy. In their study, reported ...
After a distant star's explosive death, an active stellar corpse was the likely source of repeated energetic flares observed over several months—a phenomenon astronomers had never seen before, a Cornell-led team reports ...
