Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2007 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.

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.

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.

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 ...

Fireball/Blastwave Model and Soft Gamma-ray Repeaters
, 1998 Soft gamma-ray repeaters are at determined distances and their positions are known accurately. If observed, afterglows from their soft gamma-ray bursts will provide important clues to the study of the so called "classical gamma-ray bursts".

Anisotropy in the sky distributions of the short and intermediate gamma-ray bursts: Breakdown of the cosmological principle? [PDF]
, 2009 After the discovery of the anisotropy in the sky-distribution of intermediate gamma-ray bursts recently also the distribution of the short gamma-ray bursts is proven to be anisotropic.

Bulk Lorentz factors of Gamma-Ray Bursts [PDF]
, 2017 Knowledge of the bulk Lorentz factor $\Gamma_{0}$ of GRBs allows us to compute their comoving frame properties shedding light on their physics. Upon collisions with the circumburst matter, the fireball of a GRB starts to decelerate, producing a peak or a

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.

A burst in a wind bubble and the impact on baryonic ejecta: high-energy gamma-ray flashes and afterglows from fast radio bursts and pulsar-driven supernova remnants [PDF]
, 2016 Tenuous wind bubbles, which are formed by the spin-down activity of central compact remnants, are relevant in some models of fast radio bursts (FRBs) and super-luminous supernovae.
