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…
REM observations of GRB 060418 and GRB 060607A: the onset of the afterglow and the initial fireball Lorentz factor determination
E. Molinari, S. D. Vergani, D. Malesani +32
Gamma-ray burst (GRB) emission is believed to originate in highly relativistic fireballs. Currently, only lower limits were securely set to the initial fireball Lorentz factor Gamm…
The rate and luminosity function of Short GRBs
Tsvi Piran, Dafne Guetta
We compare the luminosity function and rate inferred from the BATSE short hard bursts (SHBs) peak flux distribution with the redshift and luminosity distributions of SHBs observed…
The variable X-ray light curve of GRB 050713A: the case of refreshed shocks
D. Guetta, F. Fiore, V. D'Elia +21
We present a detailed study of the spectral and temporal properties of the X-ray and optical emission of GRB050713a up to 0.5 day after the main GRB event. The X-ray light curve ex…
