Re-born fireballs in Gamma-Ray Bursts
G. Ghisellini, A. Celotti, G. Ghirlanda +2
We consider the interaction between a relativistic fireball and material assumed to be still located just outside the progenitor star. Only a small fraction of the expected mass is…
Spectral analysis of Swift long GRBs with known redshift
J. I. Cabrera, C. Firmani, V. Avila-Reese +3
We study the spectral and energetics properties of 47 long-duration gamma-ray bursts (GRBs) with known redshift, all of them detected by the Swift satellite. Due to the narrow ener…
The role of afterglow break-times as GRB jet angle indicators
L. Nava, G. Ghisellini, G. Ghirlanda +3
The early X-ray light curve of Gamma Ray Bursts (GRBs) is complex, and shows a typical steep-flat-steep behaviour. The time T_a at which the flat (plateau) part ends may bear some…
