Supernovae and γ-Ray Bursters
Since 1997 when the first counterparts to γ-ray bursts were discovered, evidence for a connection with supernovae has accumulated. I review the status of this possible connection between γ-ray bursts and supernovae, from a mostly observational perspective. In particular I will focus on the indirect evidence provided by the energies of γ-ray bursts, the duration of the events, the event rate, the locations and environments surrounding the bursts, the discovery of X-ray lines, the signatures of circumstellar winds and, finally, the association of SN1998bw with GRB980425 and the discovery of supernova-like features in the afterglows of some γ-ray bursts.
