A Misaligned Relativistic Jet in SN 2007gr? |
||||||||||||||||||||||||||||||||||||||||||||
Abstract |
||||||||||||||||||||||||||||||||||||||||||||
| The most powerful supernovae Ib/c are believed to be connected to long duration gamma-ray burst events. Although there were clear associations between three gamma bursts and type Ib/c supernovae, not all long duration gamma bursts were related to supernovae, and not all type Ib/c supernovae have an associated GRB. It has been proposed that some of the orphan type Ib/c supernovae produce relativistic GRB jets, that are not oriented within our line of sight, explaining the lack of an observable gamma-ray burst. So far this idea has never been confirmed. We propose follow-up EVN+GBT observations of the recent SN 2007gr, which was successfully detected in an e-VLBI experiment on 6-7 September 2007. The distance of the source is only 7.3 Mpc, the closest ever radio-detected type Ib/c supernova, which makes it an ideal case to study the supernova-GRB connection. | ||||||||||||||||||||||||||||||||||||||||||||
