General relativistic simulations of compact binary mergers as engines for short gamma-ray bursts [PDF]
, 2016 Black hole—neutron star (BHNS) and neutron star—neutron star (NSNS) binaries are among the favored candidates for the progenitors of the black hole—disk systems that may be the engines powering short-hard gamma ray bursts.

The design of a gamma‐ray burst polarimeter [PDF]
, 1993 The study of the polarization properties of the gamma‐ray bursts is the one remaining unexplored avenue of research which may help to answer some of the fundamental problems regarding the nature of these mysterious objects. We have designed an instrument

The Fermi GBM gamma-ray burst time-resolved spectral catalog: brightest bursts in the first four years [PDF]
, 2016 We aim to obtain high-quality time-resolved spectral fits of gamma-ray bursts (GRBs) observed by the Gamma-ray Burst Monitor (GBM) on board the Fermi Gamma-ray Space Telescope.

Berkeley Scientific Journal, 2014 G amma R ay B ursts Bennett Stahl Many strange, incredible and explosive phenomena occur in the vast vacuum of space. Many forces are present in abundance that are more complex and powerful than imaginable; they could destroy life as we know it without leaving a trace of our existence.

Black hole neutron star coalescence as a source of gamma-ray bursts [PDF]
, 1997 We present the results of hydrodynamic (SPH) simulations showing the coalescence of a black hole with a neutron star to be a promising theoretical source of short duration gamma-ray bursts.

A revised analysis of gamma-ray bursts’ prompt efficiencies [PDF]
, 2016 The prompt Gamma-Ray Bursts' (GRBs) efficiency is an important clue on the emission mechanism producing the $\gamma$-rays. Previous estimates of the kinetic energy of the blast waves, based on the X-ray afterglow luminosity $L_X$, suggested that this ...

Optical and Near-infrared Observations of the Distant but Bright “New Year’s Burst” GRB 220101A
The Astrophysical Journal, 2023 High-redshift gamma-ray bursts (GRBs) are useful to probe the early Universe, but only a few candidates have been detected so far. Here, we report the optical and near-infrared observations of the afterglow of a relatively high-redshift event GRB 220101A,

Outliers in Spectral Time Lag-Selected Gamma Ray Bursts
Universe, 2022 It is possible that astrophysical samples are polluted by some outliers, which might belong to a different sub-class. By removing the outliers, the underlying statistical features may be revealed.

Pre-Existing Superbubbles as the Sites of Gamma-Ray Bursts [PDF]
, 2001 According to recent models, gamma-ray bursts apparently explode in a wide variety of ambient densities ranging from ~ 10^{-3} to 30 cm^{-3}. The lowest density environments seem, at first sight, to be incompatible with bursts in or near molecular clouds ...
