Light Curve Properties of Supernovae Associated With Gamma-ray Bursts

Understand

Little is known about the diversity in the light curves of GRB-SNe, including whether the light curve of SN 1998bw can be used as a representative template or whether there is a luminosity-decline rate relation akin to that of SNe Ia.

• In this paper, we aim to obtain well-constrained light curves of GRB-SNe without the assumption of empirical or parametric templates and to investigate whether the peak brightness correlates with other parameters such as the light curve shape or the time of peak.
• We select eight SNe in the redshift range 0.0085 to 0.606, which are firmly associated with GRBs.
• The light curves of these GRB-SNe are well sampled across the peak.
