By studying the spatial distribution of gamma-ray emission in the Milky Way, astronomers believe they have identified a signature of dark matter annihilation. We live…
Using the VERITAS array, astronomers have detected gamma rays from a blazar known as PKS 1441+25. The research shows that the source of the gamma…
New research form the Harvard-Smithsonian Center for Astrophysics shows that shocks in a distant gamma-ray burst originated in a supernova. Gamma-ray bursts (GRBs)–flashes of high-energy…
ESO’s La Silla and Paranal Observatories have demonstrated for the first time a link between a very long-lasting burst of gamma rays and an unusually…
NASA’s Fermi Gamma-ray Space Telescope and other satellites have recorded a record flare from a black hole at the center of the distant galaxy 3C…
A newly published study details the “missing link” between supernova explosions that generate gamma-ray bursts (GRBs) and those that don’t. Astronomers using the National Science…
The H.E.S.S. telescope system has discovered three extremely luminous gamma-ray sources in the Large Magellanic Cloud. Once again, the gamma-ray observatory H.E.S.S. has demonstrated its…
A short video details how scientists merged data on high-energy bursts seen on Earth by NASA’s Fermi Gamma-ray Space Telescope with data from ground-based radar…
Using the MAGIC telescopes at La Palma, astronomers have recorded an extreme event coming from the regions immediately surrounding a supermassive black hole located in…
New international research reveals that rare gamma-ray bursts, which can last for hours, can be explained as standard explosions occurring in a region with a…
Using NASA’s Nuclear Spectroscopic Telescope Array, astronomers have discovered a pulsar spinning five times per second and the ultimate power source of both the high-energy…
A newly published study analyzes a long-lasting blast of high-energy light, revealing that the gamma-ray burst was a rare and newly recognized class of ultra-long…
Using the Atacama Large Millimeter/submillimeter Array, astronomers have directly mapped out the molecular gas and dust in the host galaxies of gamma-ray bursts for the…
An international team of astronomers has for the first time confirmed a link between the gamma bursts and their counterparts in several radio frequencies, solving…
Using the VERITAS gamma-ray telescope, astronomers studied a mysterious VHE gamma-ray source from the constellation of Cygnus that has no known counterpart at other wavelengths….
In a new study, astronomers detail the discovery of a gamma-ray burst without a radio afterglow. Astronomers led by a Curtin University researcher have discovered…
A new study from the Harvard-Smithsonian Center for Astrophysics reveals that fast radio bursts might come from nearby flaring stars, rather than more energetic events…
