Probing the complex environments of GRB host galaxies and intervening systems: high resolution spectroscopy of GRB050922C
S. Piranomonte, P. A. Ward, F. Fiore +20
The aim of this paper is to investigate the environment of gamma ray bursts (GRBs) and the interstellar matter of their host galaxies. We use to this purpose high resolution spectr…
Jet breaks at the end of the slow decline phase of Swift GRB lightcurves
M. De Pasquale, P. Evans, S. Oates +9
The Swift mission has discovered an intriguing feature of Gamma-Ray Burst (GRBs) afterglows, a phase of shallow decline of the flux in the X-ray and optical lightcurves. This behav…
The prompt, high resolution spectroscopic view of the "naked-eye" GRB080319B
V. D'Elia, F. Fiore, R. Perna +21
GRB080319B reached 5th optical magnitude during the burst prompt emission. Thanks to the VLT/UVES rapid response mode, we observed its afterglow just 8m:30s after the GRB onset whe…
The afterglow onset for GRB060418 and GRB060607A
S. Covino, S. D. Vergani, D. Malesani +32
Gamma-ray burst are thought to be produced by highly relativistic outflows. Although upper and lower limits for the outflow initial Lorentz factor are available, observationa…
UVES/VLT High Resolution Spectroscopy of Gamma Ray Burst Afterglows
S. Piranomonte, V. D'Elia, P. Ward +2
We present early time, high resolution spectroscopy of three GRB afterglows: GRB050730, 050922C and 060418. These data give us precious information on the kinematics, ionization an…
REM observations of GRB 060418 and GRB 060607A: the onset of the afterglow and the initial fireball Lorentz factor determination
E. Molinari, S. D. Vergani, D. Malesani +32
Gamma-ray burst (GRB) emission is believed to originate in highly relativistic fireballs. Currently, only lower limits were securely set to the initial fireball Lorentz factor Gamm…
