THE THIRD FERMI GBM GAMMA-RAY BURST CATALOG: THE FIRST SIX YEARS [PDF]

open access: yes, 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.

Broad band X-ray spectral properties of Gamma-ray bursts with BeppoSAX [PDF]

open access: yes, 1997
In about one year, five gamma-ray bursts were simultaneously observed with the Wide Field Cameras and Gamma Ray Burst Monitor aboard the BeppoSAX satellite. From some of them X-ray afterglow emission has been clearly detected with the same satellite.

The Observer's Guide to the Gamma-Ray Burst-Supernova Connection [PDF]

open access: yes, 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 ...

GRB990510: on the possibility of a beamed X-ray afterglow [PDF]

open access: yes, 2000
We discuss the prompt emission of the gamma-ray burst (GRB) 990510 and its subsequent X-ray afterglow from 8.0 to 44.3 hrs after the prompt emission, using observations with the Gamma-ray Burst Monitor and Narrow Field Instruments on BeppoSAX.

In vacuo dispersion features for gamma-ray-burst neutrinos and photons [PDF]

open access: yesNature Astronomy, 2016
Over the past 15 years there has been considerable interest in the possibility of quantum-gravity-induced in vacuo dispersion, the possibility that spacetime itself might behave essentially like a dispersive medium for particle propagation.

AGILE detection of delayed gamma-ray emission from GRB 080514B [PDF]

open access: yes, 2008
GRB 080514B is the first gamma ray burst (GRB), since the time of EGRET, for which individual photons of energy above several tens of MeV have been detected with a pair-conversion tracker telescope.

Are there MeV gamma-ray bursts? [PDF]

open access: yesAIP Conference Proceedings, 1996
It is often stated that gamma-ray bursts (GRBs) have typical energies of several hundred keV. Is this a real feature of GRBs or is it due to an observational bias? We consider the possibility that bursts of a given bolometric luminosity occur with a hardness distribution $p(H)d \log H \propto H^ d \log H$. We model the detection efficiency of BATSE as

Light speed variation from gamma ray burst GRB 160509A

open access: yesPhysics 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.

Polarized Emission from Gamma-Ray Burst Jets

open access: yesGalaxies, 2017
I review how polarization signals have been discussed in the research field of Gamma-Ray Bursts (GRBs). I mainly discuss two subjects in which polarimetry enables us to study the nature of relativistic jets.
