Observational Evidence of Accretion Disk-Caused Jet Precession in Galactic Nuclei

TL;DR

This paper presents observational evidence supporting the theory that accretion disks cause jet precession in galactic nuclei, linking jet precession periods with optical luminosity in extragalactic radio sources.

Contribution

It provides empirical support for the model connecting accretion disk-induced black hole precession with observable jet precession periods.

Findings

Jet precession period correlates with optical luminosity.

Observational data supports the accretion disk precession model.

Theoretical predictions match observed relationships.

Abstract

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.
