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 $Γ_{0}$ 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…
