Analysis of X-ray flares in GRBs

D. Guetta, V. D'Elia, F. Fiore +3

We present a detailed study of the spectral and temporal properties of the X-ray flares emission of several GRBs. We select a sample of GRBs which X-ray light curve exhibits large…

Can we use Gamma Ray Bursts to probe high redshift star-formation?

F. Fiore, D. Guetta, S. Piranomonte +2

We present a detailed analysis of the selection effects that plague GRB observations. We find that these effects may partially explain the different redshift distributions between…

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…

The multiwavelength afterglow of GRB 050721: a puzzling rebrightening seen in the optical but not in the X-ray

L. A. Antonelli, V. Testa, P. Romano +27

Context. GRB050721 was detected by Swift and promptly followed-up, in the X-ray by Swift itself and, in the optical band, by the VLT operated, for the first time, in rapid response…

The variable X-ray light curve of GRB 050713A: the case of refreshed shocks

D. Guetta, F. Fiore, V. D'Elia +21

We present a detailed study of the spectral and temporal properties of the X-ray and optical emission of GRB050713a up to 0.5 day after the main GRB event. The X-ray light curve ex…
