The afterglow of the study's subject, GRB 260310A, was one of the brightest observed in a decade.
A stellar explosion that briefly outshone its entire host galaxy may have left behind a calling card no superluminous supernova has ever produced before: a burst of high-energy gamma rays detected by ...
Astronomers at the University of North Carolina at Chapel Hill have helped uncover new clues about the longest-lasting cosmic explosion ever observed, a gamma-ray burst that lasted nearly seven hours.
Cosmic rays are made primarily of protons with a few electrons sprinkled in, and they can reach energies even higher than ...
New research has failed to rule out self-annihilating dark matter as the source of a gamma-ray emission radiating from the heart of the Milky Way.
Cosmic rays are high-energy charged particles, predominantly protons and atomic nuclei, that permeate the Galaxy. As they traverse the interstellar medium, they encounter gas, dust and photon fields, ...
Binary star system supernova science just hit a milestone: a Stanford-led team using 16 years of NASA Fermi data confirmed ...
