General relativistic simulations of compact binary mergers as engines for short gamma-ray bursts [PDF]
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.

I consider various possibilities for making gamma-ray bursts, particularly from close binaries. In addition to the much-studied neutron star+neutron star and black hole+neutron star cases usually considered good candidates for short-duration bursts, there are also other possibilities.

More 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.

The design of a gamma‐ray burst polarimeter [PDF]
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

Black hole neutron star coalescence as a source of gamma-ray bursts [PDF]
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.

The Fermi GBM gamma-ray burst time-resolved spectral catalog: brightest bursts in the first four years [PDF]
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.

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.

The origin of the optical flashes: The case study of GRB 080319B and GRB 130427A [PDF]
Correlations between optical flashes and gamma-ray emissions in gamma-ray bursts have been searched in order to clarify the question whether these emissions occur at internal and/or external shocks.

A revised analysis of gamma-ray bursts’ prompt efficiencies [PDF]
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 ...
