Jet precession in the active nucleus of M81. Ongoing VLBI monitoring [Elektronisk resurs]

, 2012
In a recent publication, we reported results of a multi-frequency VLBI campaign of observations of the Active Galactic Nucleus (AGN) in galaxy M\,81, phase-referenced to the supernova SN\,1993J. We were able to extract precise information on the relative
