英文摘要A long-term variability study spanning a range of black hole mass systems, from microquasars hosting stellar-mass black holes to active galactic nuclei (AGNs) harbouring supermassive black holes, provides new insights into the physics of relativistic jets. In this work, we investigate the optical variability of both jetted and non-jetted AGNs. We apply a stochastic process known as the damped random walk to model light curves from the Zwicky Transient Facility DR23. Our results show that the mass-scaled characteristic time-scales across the black hole mass exhibit a linear relationship with a slope of similar to 0.35-0.50. This analysis confirms a previously observed correlation between the damping time-scales and black hole mass and extends it by incorporating 125 newly identified non-jetted AGNs selected from the Burst Alert Telescope AGN catalogue. The derived slope of the relation between the damping time-scales and black hole mass aligns with recent theoretical predictions, supporting the presence of a universal accretion mechanism in AGNs across different mass scales. Furthermore, our findings suggest a novel implication: the properties and production mechanisms of relativistic jets may be largely independent of black hole mass.
