The X-ray absorbing column densities of Swift Gamma-ray bursts
S. Campana, C. C. Thone, A. de Ugarte Postigo +3
Long gamma-ray bursts (GRBs) are associated with the explosion of massive stars in star forming regions. A large fraction of GRBs show intrinsic absorption as detected in optical s…
The SXI telescope on board EXIST: scientific performances
L. Natalucci, A. Bazzano, S. Campana +9
The SXI telescope is one of the three instruments on board EXIST, a multiwavelength observatory in charge of performing a global survey of the sky in hard X-rays searching for Supe…
Non variability of intervening absorbers observed in the UVES spectra of the "naked-eye" GRB080319
V. D'Elia, F. Fiore, P. Goldoni +7
The aim of this paper is to investigate the properties of the intervening absorbers lying along the line of sight of Gamma-Ray Burst (GRB) 080319B through the analysis of its optic…
UVES/VLT high resolution absorption spectroscopy of the GRB080330 afterglow: a study of the GRB host galaxy and intervening absorbers
V. D'Elia, F. Fiore, R. Perna +13
We study the Gamma Ray Burst (GRB) environment and intervening absorbers by analyzing the optical absorption features produced by gas surrounding the GRB or along its line of sight…
GRB 090423 at a redshift of z~8.1
R. Salvaterra, M. Della Valle, S. Campana +42
Gamma-ray bursts (GRBSs) are produced by rare types of massive stellar explosions. Their rapidly fading afterglows are often bright enough at optical wavelengths, that they are det…
Linking burst-only X-ray binary sources to faint X-ray transients
S. Campana
Burst-only sources are X-ray sources showing up only during short bursts but with no persistent emission (at least with the monitoring instrument which led to their discovery). The…
