		| Abstract: | 
		Supernovae were long suspected as possible progenitors of gammaray bursts. The arguments relied on circumstantial evidence. Several recent gamma-ray bursts, notably GRB 030329, have provided direct, spectroscopic evidence that supernovae and gamma-ray bursts are related. The supernovae associated with gamma-ray bursts are all of Type Ic, implying a compact progenitor, which has implications for gamma-ray burst models. Other peculiar Type Ic supernovae may help to expand understanding of the mechanisms involved. |
