UVES/VLT high resolution spectroscopy of GRB 050730 afterglow: probing the features of the GRB environment
V. D'Elia, F. Fiore, E. Meurs +44
We analyze high resolution spectroscopic observations of the optical afterglow of GRB050730, obtained with UVES@VLT about hours after the GRB trigger. The spectrum shows that the I…
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…
Archeops In-flight Performance, Data Processing and Map Making
J. F. Macias-Perez, G. Lagache, B. Maffei +69
Archeops is a balloon--borne experiment widely inspired by the Planck satellite and by its High Frequency Instrument (HFI). It is mainly dedicated to measure the Cosmic Microwave B…
The frontier of darkness: the cases of GRB 040223, GRB 040422, GRB 040624
P. D'Avanzo, P. Filliatre, P. Goldoni +23
Understanding the reasons for the faintness of the optical/near-infrared afterglows of the so-called dark bursts is essential to assess whether they form a subclass of GRBs, and he…
Optical emission from GRB 050709: a short/hard GRB in a star forming galaxy
S. Covino, D. Malesani, G. L. Israel +30
We present optical observations of the short/hard gamma-ray burst GRB 050709, the first such event with an identified optical counterpart. The object is coincident with a weak X-ra…
Open issues in gamma-ray bursts: polarimetry and dark GRBs
D. Malesani, S. Covino, E. M. Rossi +4
We review some open problems in the physics of afterglows, namely their polarization properties and the existence of dark/faint bursts. Polarization studies yield precious insights…
