The GeV emission of Gamma Ray Bursts, first detected by EGRET in an handful of bursts, is now an established property of roughly the 10% of all bursts, thanks to the Fermi/LAT observations. GRB 090510, a short burst, is particularly interesting because the good timing allows to derive a severe limit to theories of quantum gravity. With the dozen bursts detected in the 0.1-30 GeV band so far, we start to see some common properties: (i) the duration is often longer than the duration of the softer… Expand

Broad band simulation of Gamma Ray Bursts (GRB) prompt emission in presence of an external magnetic field
The origin of prompt emission in GRBs is not yet well understood. The simplest and most popular model is Synchrotron Self-Compton (SSC) emission produced by internal shocks inside anExpand
NON-THERMAL EMISSION FROM THE PHOTOSPHERES OF GAMMA-RAY BURST OUTFLOWS. I. HIGH-FREQUENCY TAILS
We study the spectrum of high-frequency radiation emerging from mildly dissipative photospheres of long-duration gamma-ray burst outflows. Building on the results of recent numerical investigations,Expand

GeV emission from gamma‐ray bursts: a radiative fireball?
We study the emission observed at energies > 100 MeV of 11 gamma-ray bursts (GRBs) detected by the Fermi-Large Area Telescope (LAT) until 2009 October. The GeV emission has three main properties: (i)Expand
The onset of the GeV afterglow of GRB 090510
We study the emission of the short/hard Gamma Ray Burst 090510 at energies >0.1 GeV as observed by the Large Area Telescope (LAT) onboard the Fermi satellite. The GeV flux rises in time as t 2 upExpand
Detection of a γ-ray burst of very long duration and very high energy
ALTHOUGH γ-ray bursts (GRBs) have been known for more than 20 years, their origin remains mysterious1. Suggestions have ranged from nearby colliding comets2 to merging neutron stars at cosmologicalExpand
SWIFT AND FERMI OBSERVATIONS OF THE EARLY AFTERGLOW OF THE SHORT GAMMA-RAY BURST 090510
We present the observations of GRB090510 performed by the Fermi Gamma-Ray Space Telescope and the Swift observatory. This is a bright, short burst that shows an extended emission detected in the GeVExpand
Fermi Observations of High-Energy Gamma-Ray Emission from GRB 080916C
TLDR
The Gamma-ray Burst Monitor and Large Area Telescope onboard the Fermi Observatory together record GRBs over a broad energy range spanning about 7 decades of gammaray energy, with the largest apparent energy release yet measured. Expand
The physics of gamma-ray bursts
Gamma-ray bursts (GRB's), short and intense pulses of low-energy $\ensuremath{\gamma}$ rays, have fascinated astronomers and astrophysicists since their unexpected discovery in the late sixties.Expand
The possible high-energy emission from GRB 080319B and origins of the GeV emission of GRBs 080514B, 080916C and 081024B
We calculate the high-energy (sub-GeV to TeV) prompt and afterglow emission of GRB 080319B that was distinguished by a naked-eye optical flash and by an unusual strong early X-ray afterglow. ThereExpand
EVIDENCE OF AN INITIALLY MAGNETICALLY DOMINATED OUTFLOW IN GRB 080916C
The composition of gamma-ray burst (GRB) ejecta is still a mystery. The standard model invokes an initially hot 'fireball' composed of baryonic matter. Here, we analyze the broadband spectra of GRBExpand
Tests of quantum gravity from observations of γ-ray bursts
The recent confirmation that at least some γ-ray bursts originate at cosmological distances suggests that the radiation from them could be used to probe some of the fundamental laws of physics. HereExpand
TESTING THE STANDARD FIREBALL MODEL OF GAMMA-RAY BURSTS USING LATE X-RAY AFTERGLOWS MEASURED BY SWIFT
We show that all X-ray decay curves of γ-ray bursts (GRBs) measured by Swift can be fitted using one or two components, both of which have exactly the same functional form comprised of an earlyExpand
