Radio Supernovae

Abstract

In this article I will briely 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 core-collapse 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 supernovae SN2004et. 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.
