ZTF LC analysis of Fermi LAT (4LAC-DR3) AGNs

Here, the damped random walk (DRW) model, implemented through Gaussian processes (GPs), is used to fit the Zwicky Transient Facility long-term optical light curves of 1684 gamma-ray emission jetted AGNs. This analysis yields one of the largest samples with characteristic optical variability timescales for jetted AGNs.

A single DRW model from GPs can fit the optical light curve of most jetted AGNs well/potentially well, while there are still some jetted AGNs whose light curve cannot be fitted well by a single DRW model. After the jet power, proxied by gamma-ray luminosity, is introduced as a new parameter, new relationships among intrinsic variability time scales, black hole mass, and jet power are discovered for efficient accretion AGNs ({tau}_in_{propto}M_BH_^0.29-0.06+0.06^P_jet_^-0.3-0.03+0.03^ with scatter of approximately 0.09 dex) and for inefficient accretion AGNs ({tau}_in_{propto}M_BH_^0.06-0.07+0.07^P_jet_^0.37-0.11+0.11^ with scatter of approximately 0.14 dex), respectively.
