摘要:We present the results of the ongoing investigation of the compact radio sources within the central kpc of M82. The most recent global VLBI observations at 1.7 and 5 GHz, attaining an angular resolution of 4 mas and 1 mas respectively, have been used to image the unusual source 41.95+57.5. Previous global VLBI observations at 1.7GHz from 2005 have also been combined with archival VLBI and EVN observations to monitor the expansion of the supernova remnant 43.31+59.2. We also discuss the combination of these global data with simultaneous MERLIN observations.
