Strong radio emission from SN 2007bg one year after the explosion - detection of spreading, off-axis GRB jet?
Abstract
In their study of supernova hosts using SDSS data (Prieto, Stanek & Beacom 2008, ApJ, 673, 999), the broad-lined SN Ic 2007bg at z=0.034 (Quimby et al. 2007, #CBET 927; Harutyunyan et al. 2007, CBET #948; Soderberg & Immler 2007, ATEL #1142), was identified as a good candidate for an off-axis GRB. The likely host of SN 2007bg is an extremely low- luminosity galaxy with M_B ~ -12, one of the least-luminous supernova hosts of any kind ever observed.
