Abstract:
We compiled a sample of 73 active galactic nuclei (AGNs) with
reverberation mapping (RM) observations from RM campaigns, including
our ongoing campaign of monitoring super-Eddington accreting massive
black holes (BHs). This sample covers a large range of BH mass
(M•=106-9^M☉), dimensionless accretion rates
(dM/dt=10-2.7-102.7), and 5100Å luminosity
(L5100=1042-46erg/s), allowing us to systematically study the AGN
variability and their relations with BH mass, accretion rates, and
optical luminosity. We employed the damped random walk (DRW) model to
delineate the optical variability of continuum at 5100Å and
obtained damped variability timescale (τd) and amplitude
(σd) using a Markov Chain Monte Carlo method. We also
estimated the traditional variability amplitudes (Fvar), which
provide a model-independent measure and therefore are used to test the
DRW results. We found that AGN variability characteristics are
generally correlated with (M•, dM/dt, L5100). These
correlations are smooth from sub-Eddington to super-Eddington
accretion AGNs, probably implying that the AGN variability may be
caused by the same physical mechanism.
