Some gamma-ray bursts (GRBs) have a tera–electron volt (TeV) afterglow, but the early
onset of this has not been observed. We report observations with the Large High Altitude Air …

We report the discovery of GRB 221009A, the highest flux gamma-ray burst (GRB) ever
observed by the Fermi Gamma-ray Burst Monitor (Fermi-GBM). This GRB has continuous …

GRB 221009A has been referred to as the brightest of all time (BOAT). We investigate the
veracity of this statement by comparing it with a half century of prompt gamma-ray burst …

Long-duration gamma-ray bursts (GRBs) are powerful cosmic explosions, signaling the
death of massive stars. Among them, GRB 221009A is by far the brightest burst ever …

We report on Konus-WIND (KW) and Mikhail Pavlinsky Astronomical Roentgen Telescope–
X-ray Concentrator (ART-XC) observations and analysis of a nearby GRB 221009A, the …

We report the discovery of the unusually bright long-duration gamma-ray burst (GRB), GRB
221009A, as observed by the Neil Gehrels Swift Observatory (Swift), Monitor of All-sky X-ray …

Abstract GRB 221009A (z= 0.151) is one of the closest known long γ-ray bursts (GRBs). Its
extreme brightness across all electromagnetic wavelengths provides an unprecedented …

We discuss implications that can be obtained by searches for neutrinos from the brightest
gamma-ray burst (GRB), GRB 221009A. We derive constraints on GRB model parameters …

Gamma-ray bursts (GRBs) have long been considered a possible source of high-energy
neutrinos. While no correlations have yet been detected between high-energy neutrinos and …

Abstract We present James Webb Space Telescope (JWST) and Hubble Space Telescope
(HST) observations of the afterglow of GRB 221009A, the brightest gamma-ray burst (GRB) …
