The evolution of SN 2008iz in M82

Abstract

The recent discovery of supernova 2008iz in the nearby galaxy M82 offers the opportunity to observe this rare event in great detail. We propose to continue our monitoring of the evolution of the recently discovered supernova 2008iz in M82 with the VLBA, Effelsberg, and the GBT at frequencies from 1.6 to 8 GHz. The observations should be conducted every four months over the next year and will allow us to observe the expansion of the supernova shockwave into the interstellar medium. Following the expansion of the ring together with EVLA monitoring will allow us to study many different phenomena, e.g. measure the expansion speed, the deceleration of the shock front, and the proper motion of the supernova shell relative to M81, get more information on the structure of the circumstellar medium, the evolution of the magnetic field, and the importance of radiative (and/or synchrotron self-absorption) losses. Furthermore, it will allow a detailed comparison with SN1993J, the other radio supern
