A Universal Central Engine Hypothesis for Short and Long GRBs
David Eichler, Dafne Guetta, Hadar Manis
It is noted that X-ray tails (XRTs) of short, hard -ray bursts (SHBs) are similar to X-ray flashes (XRFs). We suggest a universal central engine hypothesis, as a way of accounti…
The complex light-curve of the afterglow of GRB071010A
S. Covino, P. D'Avanzo, A. Klotz +51
We present and discuss the results of an extensive observational campaign devoted to GRB071010A, a long-duration gamma-ray burst detected by the Swift satellite. This event was fol…
The prompt, high resolution spectroscopic view of the "naked-eye" GRB080319B
V. D'Elia, F. Fiore, R. Perna +21
GRB080319B reached 5th optical magnitude during the burst prompt emission. Thanks to the VLT/UVES rapid response mode, we observed its afterglow just 8m:30s after the GRB onset whe…
On the Rates of Gamma Ray Bursts and Type Ib/c Supernovae
Dafne Guetta, Massimo Della Valle
We measure the local rates of ``low-luminosity'' (LL-GRBs, i.e. L<10^{48--49}erg/sec) and ``high-luminosity'' Gamma-ray Bursts (HL-GRBs). The values are in the range n0=100--1800 G…
