The GRB-SN association

摘要

Long-duration gamma ray bursts (GRBs) and X-ray flashes (XRFs) appear to be produced by highly relativistic and narrowly collimated jets ejected in core collapse supernova (SN) explosions akin to SN1998bw. We review the history of the GRB-SN association idea and its observational verification. We summarize the present evidence for a GRB/XRF-SN association. We comment on the possibility that most, perhaps all, SN explosions produce GRBs, including SNe of Type Ia which may produce short GRBs/XRFs. We list the major open questions that follow from a GRB/XRF-SN association. Possible uses of the GRB-SN association in cosmology are pointed out.
