Recent Observations of GRB-Supernovae

Abstract

Abstract. The GRB-SNe connection has been strengthened since 2008 by the detection of 6 additional GRB-SNe at both local and cosmological redshifts. This review summarizes the recent observations of SNe associated with GRBs 081007, 090618, 091127, 100316D, 101219B and 111211A, as well as the observations of SN 2008D, which was associated with a bright X-ray flash (XRF 080109) and may represent a link between "plain" SN and GRB-SNe. It is now clear that most -if not all -long-duration GRBs are produced by the core collapse of massive stars.
