Functional biases in GRB's spectral parameter correlations
F. Massaro, S. Cutini, M. L. Conciatore +1
Gamma Ray Bursts (GRBs) show evidence of different spectral shapes, light curves, duration, host galaxies and they explode within a wide redshift range. However, the most of them s…
Swift GRBs: the early afterglow spectral energy distribution
G. Tagliaferri, D. Malesani, S. D. Vergani +16
We present the first results of a program to systematically study the optical-to-X-ray spectral energy distribution (SED) of Swift GRB afterglows with known redshift. The goal is t…
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…
GRB 050904 at redshift 6.3: observations of the oldest cosmic explosion after the Big Bang
G. Tagliaferri, L. A. Antonelli, G. Chincarini +10
We present optical and near-infrared observations of the afterglow of the gamma-ray burst GRB 050904. We derive a photometric redshift z = 6.3, estimated from the presence of the L…
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…
GRB environment properties through X and optical afterglow observations
M. L Conciatore, L. A. Antonelli, G. Stratta +2
We present the spectral analysis of 14 gamma-ray bursts (GRB) X-ray afterglows in order to investigate the properties of interstellar matter (ISM) along the line of sight of GRB. W…
