Vreeswijk ( University of Alabama in Huntsville, NASA/Marshall Space Flight Center, University o | | Abstract: | The recent discovery of a supernova (SN 1998bw) seemingly associated with GRB~980425 adds a new twist to the decades-old debate over the origin of gamma-ray bursts. To investigate the possibility that some (or all) bursts are associated with supernovae, we performed a systematic search for temporal/angular correlations using catalogs of BATSE and BATSE/{it Ulysses} burst locations. We find no associations with any of the precise BATSE/{it Ulysses} locations, which allows us to conclude that the fraction of high-fluence gamma-ray bursts from known supernovae is small ($<$0.2%). For the more numerous weaker bursts, the corresponding limiting fraction of 1.5% is less constraining due to the imprecise locations of these events. This limit ($1.5% simeq 18$ bursts) allows that a large fraction of the recent supernovae used as a comparison data set (18 supernovae $simeq 20%$) could have associated gamma-ray bursts. Thus, although we find no significant evidence to support a burst/supernova association, the possibility cannot be excluded for weak bursts. | | Source: | arXiv, astro-ph/9806364 | | Services: | Forum | Review | PDF | Favorites | |
