Abstract
MERLIN and VLA observations of the galaxy M82 have detected a jet-like elongated radio continuum feature emanating from one of the compact sources, 44.01+59.6, embedded in the starburst. The proximity of this source to the dynamical centre of M82 led us to suspect that it could be a weak active nucleus rather than a supernova remnant. We have imaged this source using the EVN at 15 mas and, although it shows a compact shell-like structure which could be consistent with a supernova remnant, we note that the image shows a bright region within the source which is elongated along the jet direction. There are distinct similarities between this source and the Sgr A complex in the centre of our own Galaxy, and by analogy we suggest that 44.01+59.6 may also harbour a weak active galactic nucleus.
