A Millimeter Rebrightening in GRB 210702A

open access: yesThe Astrophysical Journal
We present X-ray to radio frequency observations of the bright long gamma-ray burst GRB 210702A. Our Atacama Large Millimeter/submillimeter Array 97.5 GHz observations show a significant rebrightening by a factor of ≈2 beginning at 8.2 days post-burst ...

Gamma ray bursts: A review of recent high-precision measurements [PDF]

open access: yes
Recent measurements and discoveries in gamma ray bursts and transients are reviewed including observations of the red shifted annihilation line in two kinds of slow transients (in 'classical' gamma ray bursts and in the unique 1979 March 5th event); of ...

Correlation between Peak Energy and Peak Luminosity in Short Gamma-Ray Bursts

open access: yes, 2012
A correlation between the peak luminosity and the peak energy has been found by Yonetoku et al. as $L_{p}\propto E_{p,i}^{2.0}$ for 11 pre-Swift long gamma-ray bursts. In this study, for a greatly expanded sample of 148 long gamma-ray bursts in the Swift

A Subclass of Gamma-Ray Burst Originating from Compact Binary Merger

open access: yesThe Astrophysical Journal
Type I gamma-ray bursts (GRBs) are believed to originate from compact binary mergers usually with a duration of main emission less than 2 s. However, recent observations of GRB 211211A and GRB 230307A indicate that some merger-origin GRBs could last much

Gamma-ray burst variability above 4 MeV [PDF]

open access: yes
The relationship between the hard X-ray and gamma ray emissions during four bursts using the anti-coincidence shields of the High Energy Astronomy Observatory 3 (HEAO 3) Gamma Ray Spectrometer is explored.

Analysis of Gamma-Ray Burst Closure Relationship in Multiple Wavelengths

open access: yesThe Astrophysical Journal
Gamma-ray bursts (GRBs) are intense pulses of high-energy emission associated with the death of massive stars or compact objects’ coalescence. Their multiwavelength observations help verify the reliability of the standard fireball model.

Contribution of γ-Ray Burst Afterglow Emissions to the Isotropic Diffuse γ-Ray Background

open access: yesThe Astrophysical Journal
The isotropic diffuse γ -ray background (IGRB) serves as a fundamental probe of the evolution of the extreme Universe. Although various astrophysical sources have been proposed as potential contributors to the IGRB, the dominant population is still under
