Observational Evidence of Jet Precession in Galactic Nuclei Caused by Accretion Disks

We show that the observational data of extragalactic radio sources tend to support the theoretical relationship between the jet precession period and the optical luminosity of the sources, as predicted by the model in which an accretion disk causes the central black hole to precess.
