M94 as a Unique Testbed for Black Hole Mass Estimates and AGN Activity at Low Luminosities
We discuss the peculiar nature of the nucleus of M94 (NGC 4736) in the context of new measurements of the broad Hα emission from HST-STIS observations. We show that this component is unambiguously associated with the high-resolution X-ray, radio, and variable UV sources detected at the optical nucle...
