THE THIRD FERMI GBM GAMMA-RAY BURST CATALOG: THE FIRST SIX YEARS [PDF]
, 2016 Since its launch in 2008, the Fermi Gamma-ray Burst Monitor (GBM) has triggered and located on average approximately two γ-ray bursts (GRBs) every three days.

Light speed variation from gamma ray burst GRB 160509A
Physics Letters B, 2016 It is postulated in Einstein's relativity that the speed of light in vacuum is a constant for all observers. However, the effect of quantum gravity could bring an energy dependence of light speed.

Observations of GRB 990123 by the Compton Gamma-Ray Observatory [PDF]
, 1999 GRB 990123 was the first burst from which simultaneous optical, X-ray and gamma-ray emission was detected; its afterglow has been followed by an extensive set of radio, optical and X-ray observations.

THE FERMI GAMMA-RAY BURST MONITOR [PDF]
, 2009 The Gamma-Ray Burst Monitor (GBM) will significantly augment the science return from the Fermi Observatory in the study of gamma-ray bursts (GRBs). The primary objective of GBM is to extend the energy range over which bursts are observed downward from ...

Gamma-Ray Burst Energetics [PDF]
The Astrophysical Journal, 1999 We estimate the fraction of the total energy in a Gamma-Ray Burst (GRB) that is radiated in photons during the main burst. Random internal collisions among different shells limit the efficiency for converting bulk kinetic energy to photons. About 1% of the energy of explosion is converted to radiation, in 10-1000 kev energy band in the observer frame ...

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.

The Observer's Guide to the Gamma-Ray Burst-Supernova Connection [PDF]
, 2016 We present a detailed report of the connection between long-duration gamma-ray bursts (GRBs) and their accompanying supernovae (SNe). The discussion presented here places emphasis on how observations, and the modelling of observations, have constrained ...

Afterglows as Diagnostics of Gamma Ray Burst Beaming [PDF]
, 1997 If gamma ray bursts are highly collimated, radiating into only a small fraction of the sky, the energy requirements of each event may be reduced by several (up to 4 - 6) orders of magnitude, and the event rate increased correspondingly. The large Lorentz

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.
