GRB 221009A: Discovery of an Exceptionally Rare Nearby and Energetic Gamma-Ray Burst
The Astrophysical Journal Letters, 2023 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 Image, and Neutron Star Interior Composition Explorer Mission.

THE COSMIC GAMMA-RAY BURSTS [PDF]
The Ninth Marcel Grossmann Meeting, 2002 Cosmic gamma-ray bursts are one of the great frontiers of astrophysics today. They are a playground of relativists and observers alike. They may teach us about the death of stars and the birth of black holes, the physics in extreme conditions, and help us probe star formation in the distant and obscured universe. In this review we summarise some of the

Anisotropy of the sky distribution of gamma-ray bursts [PDF]
, 1998 The isotropy of gamma-ray bursts collected in current BATSE catalog is studied. It is shown that the quadrupole term being proportional to \sim sin 2b sin l is non-zero with a probability of 99.9%. The occurrence of this anisotropy term is then confirmed

Model Constraints Based on the IceCube Neutrino Nondetection of GRB 221009A
The Astrophysical Journal, 2023 GRB 221009A is a bright gamma-ray burst (GRB) with isotropic energy larger than 10 ^54 erg. Its fairly low redshift makes it a promising candidate for high-energy neutrino detection.

Repeating Emission Episodes in Gamma-Ray Bursts: Millilensing or Jet Precession?
The Astrophysical Journal, 2023 Recently, some gamma-ray bursts (GRBs) whose light curves consist of repeating emission episodes with similar temporal profiles have attracted extensive attention.

Are there MeV gamma-ray bursts? [PDF]
AIP Conference Proceedings, 1996 It is often stated that gamma-ray bursts (GRBs) have typical energies of several hundred keV. Is this a real feature of GRBs or is it due to an observational bias? We consider the possibility that bursts of a given bolometric luminosity occur with a hardness distribution $p(H)d \log H \propto H^γd \log H$.

UniverseMore than fifty years have elapsed from the first discovery of gamma-ray bursts (GRBs) with American Vela satellites, and more than twenty-five years from the discovery with the BeppoSAX satellite of the first X-ray afterglow of a GRB.
