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.

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

, 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]

, 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]

, 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]

Nature 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]

, 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]

AIP 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

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.

Polarized Emission from Gamma-Ray Burst Jets

Galaxies, 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.
