GRB 221009A was an extraordinarily bright and very energetic gamma-ray burst (GRB) jointly discovered by the Neil Gehrels Swift Observatory and the Fermi Gamma-ray Space Telescope …

2023年3月28日 · GRB 221009A is the BOAT by three of the four measures of brightness. It is certainly the highest fluence and peak flux GRB ever identified, by a large margin. It is the …

2024年9月6日 · We present a complete analysis of Fermi Large Area Telescope (LAT) data of GRB 221009A, the brightest Gamma-Ray Burst (GRB) ever detected. The burst emission …

2024年7月25日 · In October 2022, astronomers were stunned by what was quickly dubbed the BOAT — the brightest-of-all-time gamma-ray burst (GRB). Now an international science team …

2023年2月27日 · GRB 221009A has been referred to as the Brightest Of All Time (the BOAT). We investigate the veracity of this statement by comparing it with a half century of prompt gamma …

2023年6月8日 · Scientists may finally know what made the largest explosion in the universe ever seen by humankind so powerful. Astronomers have discovered that the brightest gamma-ray …

2024年8月29日 · We present radio observations of the long-duration gamma-ray burst (GRB) 221009A which has become known to the community as the Brightest Of All Time or the …

2022年10月28日 · This new burst, officially named GRB 221009A, was probably triggered by a supernova giving birth to a black hole in a galaxy about 2 billion light-years from Earth, …

2023年3月28日 · Radiation from the explosion — a gamma-ray burst (GRB) known as GRB 221009A — swept over Earth on Oct. 9, 2022. It saturated gamma-ray detectors on multiple …

Unexpectedly, GRB 221009A has the highest isotropic-equivalent total energy ever identified, while the peak luminosity is at the ∼99th percentile of the known distribution. We explore how …
