GRB 070311: a direct link between the prompt emission and the afterglow
C. Guidorzi, S. D. Vergani, S. Sazonov +30
We present prompt gamma-ray, early NIR/optical, late optical and X-ray observations of the peculiar GRB 070311 discovered by INTEGRAL, in order to gain clues on the mechanisms resp…
Testing the gamma-ray burst variability/peak luminosity correlation on a Swift homogeneous sample
D. Rizzuto, C. Guidorzi, P. Romano +10
We test the gamma-ray burst correlation between temporal variability and peak luminosity of the -ray profile on a homogeneous sample of 36 Swift/BAT GRBs with firm redshift dete…
Swift observations of GRB 060614: an anomalous burst with a well behaved afterglow
V. Mangano, S. T. Holland, D. Malesani +22
GRB 060614 is a remarkable GRB observed by Swift with puzzling properties, which challenge current progenitor models. The lack of any bright SN down to very strict limits and the v…
Are Swift gamma-ray bursts consistent with the Ghirlanda relation?
S. Campana, C. Guidorzi, G. Tagliaferri +4
A few tight correlations linking several properties of gamma-ray bursts (GRBs), namely the spectral peak energy, the total radiated energy, and the afterglow break time, have been…
The First Survey of X-ray Flares from Gamma Ray Bursts Observed by Swift: Temporal Properties and Morphology
G. Chincarini, A. Moretti, P. Romano +24
We present the first systematic investigation of the morphological and timing properties of flares in GRBs observed by Swift/XRT. We consider a large sample drawn from all GRBs det…
Dust and Gas in the Local Environments of Gamma-Ray Bursts
P. Schady, K. O. Mason, M. J. Page +6
Using a sample of gamma-ray burst (GRB) afterglows detected by both the X-Ray and the UV/Optical Telescopes (XRT and UVOT) on Swift, we modelled the spectral energy distributions (…
