Prospects for detection of very high-energy emission from GRB in the context of the external shock model
A. Galli, L. Piro
The detection of the 100 GeV-TeV emission by a gamma-ray burst (GRB) will provide an unprecedented opportunity to study the nature of the central engine and the interaction between…
On the nature of X-Ray Flashes in the SWIFT era
B. Gendre, A. Galli, L. Piro
X-Ray Flashes (XRFs) are soft gamma-ray bursts whose nature is not clear. Their soft spectrum can be due to cosmological effects (high redshift), an off-axis view of the jet or can…
Hypernova Signatures in the Late Rebrightening of GRB 050525A
M. Della Valle, D. Malesani, J. S. Bloom +22
We report observations of GRB 050525A, for which a Gemini North spectrum shows its redshift to be z = 0.606. This is the third closest long GRB discovered by Swift. We observed its…
Properties of X-Ray Rich Gamma Ray Bursts and X-Ray Flashes detected with BeppoSAX and Hete-2
V. D' Alessio, L. Piro, E. M. Rossi
We study the spectrum of the prompt emission and the X-ray and optical afterglow fluxes of 54 X-Ray Rich Gamma Ray Burst (XRRs) and X-Ray Flashes (XRFs), observed by BeppoSax and H…
Multi-wavelength analysis of the field of the dark burst GRB 031220
A. Melandri, B. Gendre, L. A. Antonelli +8
We have collected and analyzed data taken in different spectral bands (from X-ray to optical and infrared) of the field of GRB031220 and we present results of such multiband observ…
The GRB of 1999 January 23: prompt emission and broad-band afterglow modeling
A. Corsi, L. Piro, E. Kuulkers +13
We report on BeppoSAX simultaneous X- and gamma-ray observations of the bright gamma-ray burst (GRB) 990123. We present the broad-band spectrum of the prompt emission, including op…
