Radio emission from the cocoon of a GRB jet: implications for relativistic supernovae and off-axis GRB emission

Fabio De Colle, Pawan Kumar, David R. Aguilera-Dena

Relativistic supernovae constitute a sub-class of type Ic supernovae (SNe). Their non-thermal, radio emission differs notably from that of regular type Ic supernovae as they have a…
