Radio supernovae

Abstract

I will briefly review the current status of radio observations of nearby supernovae and their remnants. This review will initially address observations of the radio 'light' curves of nearby corecollapse supernovae, followed by a more detailed summary of recent Very Long Baseline Interferometric observations of the expansion of nearby supernovae and their remnants. These later sections will concentrate on a few sources, namely those found in M82, SN1993J, and the recent supernova 2004et. In addition, I will discuss the many radio detections of supernovae found in the highly obscured centres of starburst galaxies, such as M82 and Arp220, where no optical detections are possible.
