Abstract:
The radius-luminosity (RHβ-L5100) relationship of active
galactic nuclei (AGNs) established by the reverberation mapping (RM)
observations has been widely used as a single-epoch black hole mass
estimator in the research of large AGN samples. However, the recent RM
campaigns discovered that the AGNs with high-accretion rates show
shorter time lags by factors of a few comparing with the predictions
from the RHβ-L5100 relationship. The explanation of the
shortened time lags has not been finalized yet. We collect eight
different single-epoch spectral properties to investigate how the
shortening of the time lags correlates with those properties and to
determine the origin of the shortened lags. We find that the flux
ratio between FeII and Hβ emission lines shows the most prominent
correlation, thus confirming that accretion rate is the main driver
for the shortened lags. In addition, we establish a new scaling
relation including the relative strength of FeII emission. This new
scaling relation can provide less biased estimates of the black hole
mass and accretion rate from the single-epoch spectra of AGNs.
