Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered a supernova explosion accompanying the gamma-ray burst event GRB 250314A...
High-energy photons produced deep in gamma-ray burst jets emerging from a collapsed star could dissolve the outer stellar layers into free neutrons, causing...
Using sensitive instruments onboard ESA’s International Gamma-Ray Astrophysics Laboratory (Integral) mission, astronomers have detected a gamma-ray burst...
Using satellite observations, including from ESA’s International Gamma-Ray Astrophysics Laboratory (Integral) mission, and a new developed analytical...
Using an array of ground and space-based telescopes, including the NASA/ESA/CSA James Webb Space Telescope, NASA’s Fermi Gamma-ray Space Telescope, and...
Unlike most gamma-ray bursts, which are caused by exploding massive stars or the chance mergers of neutron stars, a long gamma-ray burst event dubbed GRB...
Using data from NASA’s Fermi Gamma-ray Space Telescope and the IceCube Neutrino Observatory, astrophysicists have found preliminary evidence for gamma-ray...
Astronomers have provided vital information in the global effort to understand GRB 221009A, one of the nearest and possibly the most-energetic gamma-ray...
Astronomers have examined data about 700 short gamma-ray bursts (GRBs) detected with NASA’s Neil Gehrels Swift Observatory, Fermi Gamma-ray Space Telescope,...
Gamma-ray bursts (GRBs) come in two varieties, long and short. Long GRBs, which last a couple of seconds to one minute, form when a star at least 10 times...
GRB 221009A, a gamma-ray burst detected on October 9, 2022, is one of the nearest and possibly the most-energetic gamma-ray burst ever observed. It occurred...
Astronomers using the X-SHOOTER instrument at ESO’s Very Large Telescope (VLT) have detected light from a gamma-ray burst at a redshift of 6.3, meaning...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have for the first time detected the millimeter afterglow of a short-duration...
About 30% of short gamma-ray bursts (sGRBs), which form during the collisions of neutron stars, lack a coincident host galaxy, raising questions about...
The giant gamma-ray flare event, designated GRB 2001415, was emitted by a powerful magnetar in NGC 253, an active starburst galaxy approximately 11 million...
Most known supernova-powered gamma-ray bursts are ‘long’ (lasting more than two seconds), but a gamma-ray burst event called GRB 200826A lasted just...
Long gamma-ray bursts are bright flashes of extragalactic gamma rays produced during the collapse of a massive star. A gamma-ray burst itself lasts only...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) exoplanet-hunting mission have detected the rising and decaying optical afterglow...
A gravitationally lensed gamma-ray burst, designated GRB 950830, helped astronomers detect a black hole about 55,000 times more massive than the Sun.
An...
An international of astronomers has observed an optical afterglow of a short gamma-ray burst, thought to be from the merger of two neutron stars, and localized...
