Electromagnetic Transients from Supernovae

A core-collapse supernova (SN) would produce an expanding shell of charged particles which interact with the surrounding magnetic field of the progenitor star producing a transient radio pulse. Approximately one supernova event per century is expected in a galaxy. Such a pulse may be detected by a transient radio array. We present details of an ongoing such for such events by the Eight-meter-wavelength Transient Array (ETA).
