Prompt high-energy emission from gamma-ray bursts in the internal shock model
Z. Bosnjak, F. Daigne, G. Dubus
The prompt GRB emission is thought to arise from electrons accelerated in internal shocks propagating within a highly relativistic outflow. The launch of Fermi offers the prospect…
Black-body components in Gamma-Ray Bursts spectra?
G. Ghirlanda, Z. Bosnjak, G. Ghisellini +2
We study 7 Gamma Ray Bursts (GRBs), detected both by the BATSE instrument, on-board the Compton Gamma Ray Observatory, and by the Wide Field Camera (WFC), on-board BeppoSAX. These…
Are GRB 980425 and GRB 031203 real outliers or twins of GRB 060218?
G. Ghisellini, G. Ghirlanda, S. Mereghetti +3
GRB 980425 and GRB 031203 are apparently two outliers with respect to the correlation between the isotropic equivalent energy E_iso emitted in the prompt radiation phase and the pe…
GRB 990413: Insight into the thermal phase evolution
Z. Bosnjak, A. Celotti, G. Ghirlanda
GRB 990413 shows a very hard spectrum (with a low energy spectral component F(E) \propto E^{2.49}) which is well represented by a black body model with characteristic temperature ~…
Gamma--Ray Bursts associated with Supernovae: A systematic analysis of BATSE GRB candidates
Z. Bosnjak, A. Celotti, G. Ghirlanda +2
We examined the properties of a sample of BATSE Gamma--Ray Bursts (GRBs) comprising events which have indications of association with a supernova (SN), some on the basis of indicat…
Energetics - Spectral correlations vs the BATSE Gamma-Ray Bursts population
Z. Bosnjak, A. Celotti, F. Longo +1
Recently proposed correlations between the energetics of Gamma-Ray Bursts (GRB) and their spectral properties, namely the peak energy of their prompt emission, are found to account…
