Abstract
In this paper wecomparetheobse rved radial distributions of Gamma Ray Bursts and of Supernovæ with respect to the host galaxy center. We investigate the possibility that the observed Gamma Ray Burst offset distribution (in kpc) is in fact the distribution of I-b/c supernovæ modified by the kick received by the binary system when the first supernova explosion occurs. Our analysis lends support to the scenario in which all long-duration GRBs are produced by type Ib/c SNe. We ruled out that a significant fraction of long-duration GRBs could be due to merging of compact remnants of stellar evaluation.
