Flares in Gamma Ray Bursts (II)
G. Chincarini, R. Margutti, J. Mao +4
We illustrate some of the preliminary results obtained with a new sample of flares and a new analysis. In these proceedings we deal mainly with the analysis related to the flare en…
Flares in Gamma Ray Bursts
G. Chincarini, J. Mao, F. Pasotti +4
The flare activity that is observed in GRBs soon after the prompt emission with the XRT (0.3-10 KeV) instrument on board of the Swift satellite is leading to important clues in rel…
Temporal variability of GRB early X-ray afterglows and GRB080319B prompt emission
R. Margutti, C. Guidorzi, G. Chincarini +3
We performed the first systematic search for the minimum variability time scale between 0.3 and 10 keV studying the 28 brightest early (<3000 s) afterglows detected by Swift-XRT up…
The metamorphosis of Supernova SN2008D/XRF080109: a link between Supernovae and GRBs/Hypernovae
Paolo A. Mazzali, Stefano Valenti, Massimo Della Valle +38
The only supernovae (SNe) to have shown early gamma-ray or X-ray emission thus far are overenergetic, broad-lined Type Ic SNe (Hypernovae - HNe). Recently, SN 2008D shows several n…
Anomalous X-Ray emission in GRB060904B: a Nickel line?
R. Margutti, A. Moretti, F. Pasotti +6
The detection of an extra component in GRB060904B X-ray spectra in addition to the standard single power-law behaviour has recently been reported in the literature. This component…
When GRB afterglows get softer, hard components come into play
A. Moretti, R. Margutti, F. Pasotti +9
We aim to investigate the ability of simple spectral models to describe the GRB early afterglow emission. We performed a time resolved spectral analysis of a bright GRB sample dete…
