SN 1998bw SN 1998bw was a rare broad-lined Type Ic gamma ray burst supernova detected on 26 April 1998 in the ESO 184-G82 spiral galaxy, which some astronomers believe may be an example of a collapsar.〔(【引用サイトリンク】title=Gamma-Ray Supernova 1998bw )〕 The supernova has been linked to GRB 980425, which was detected on 25 April 1998, the first time a gamma-ray burst has been linked to a supernova. The supernova is approximately 140 million light years away, very close for a gamma ray burst source.〔(【引用サイトリンク】title=A Strange Supernova with a Gamma-Ray Burst )〕 ==References==
