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…
The host galaxy of GRB031203: a new spectroscopic study
R. Margutti, G. Chincarini, S. Covino +11
The host galaxy of the long-duration gamma-ray burst (GRB) 031203 (HG031203) offers a precious opportunity to study in detail the environment of a nearby GRB. The aim is to better…
The optical counterpart of IGR J00291+5934 in quiescence
P. D'Avanzo, S. Campana, S. Covino +3
The recent (December 2004) discovery of the sixth accretion-powered millisecond X-ray pulsar IGR J00291+5934 provides a very good chance to deepen our knowledge of such systems. Al…
The First Survey of X-ray Flares from Gamma Ray Bursts Observed by Swift: Spectral Properties and Energetics
A. D. Falcone, D. Morris, J. Racusin +12
Observations of gamma ray bursts (GRBs) with Swift produced the initially surprising result that many bursts have large X-ray flares superimposed on the underlying afterglow. The f…
Multicolor observations of the afterglow of the short/hard GRB 050724
D. Malesani, S. Covino, P. D'Avanzo +19
New information on short/hard gamma-ray bursts (GRBs) is being gathered thanks to the discovery of their optical and X-ray afterglows. However, some key aspects are still poorly un…
