TL;DR: The first indications of a class of long GRBs are presented, which form a bridge between the typical high-luminosity, high-redshift events and nearby low- luminosity events (which are also associated with spectroscopic supernovae) in terms of energetics and observed redshift distribution, indicating a continuous distribution overall.

TL;DR: In this paper, an optical and near-infrared (NIR) photometry for three gamma-ray burst supernovae (GRB-SNe): GRB 120729A, GRB 130215A/SN 2013ez, and GRB130831A/N 2013fu was presented, which indicated an unusually low expansion velocity of ~4000-6350 km's-1, the lowest ever measured for a GRB-SN.
