The supernova associated with GRB 020405.

DADO S., DAR A. and DE RUJULA A.

Abstract (from CDS):

We use the very simple and successful Cannonball (CB) model of gamma ray bursts (GRBs) and their afterglows (AGs) to analyze the observations of the mildly extinct optical AG of the relatively nearby GRB 020405. We show that GRB 020405 was associated with a 1998bw-like supernova (SN) at the GRB's redshift that appeared dimmer and redder than SN1998bw because of extinction in the host and our Galaxy. The case for the SN/GRB association - advocated in the CB model - is becoming indubitable. We discuss the extent to which the GRB/SN connection is model-dependent.
