Intermediate-mass black holes are theoretically predicted but observationally elusive. They are potentially the seeds of supermassive black holes in the early universe, and yet conclusive evidence for them is proving exceedingly difficult to obtain. The nearby face-on spiral galaxy NGC3310 has hosted many supernovae in recent history, and recent Chandra observations have shown a group of strong off-nuclear x-ray sources that are coincident with radio emission seen in archival radio observations with VLA and MERLIN. Their luminosity, spectrum and off-nuclear location make these sources excellent IMBH candidates. To investigate this possibility, we used combined EVN/e-MERLIN observations at both 1.4 and 5 GHz to look for compact radio emission and evidence of jet activity. I will show the results of our ongoing investigations and the potential implications for IMBH parameter space.
