Content

The nearby supernova factory M82 has been intensely studied by e-MERLIN and other radio interferometers over the last 4 decades. The high optical absorption in M82 has prevented study of the supernovae, HII regions and exotic transient objects in this galaxy in optical bands. However, the increased sensitivity from e-MERLIN and the EVN has provided new data and enabled the study of more sources.

In this oral contribution, we give an update on the current efforts to monitor this source, including re-analysis of 2014 e-MERLIN data to provide resolved spectral index maps using new widefield imaging techniques, the renewed search for transient sources further afield at the edges of the optical extent of the galaxy, and, provide the results of the latest tranche of e-MERLIN and EVN monitoring efforts in recent years.
