cds-question@unistra.fractive-galactic-nucleiline-intensitiesblack-holesspectroscopyvisible-astronomyThe radius-luminosity (R_H{beta}_-L_5100_) 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 R_H{beta}_-L_5100_ 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 H{beta} 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.2019ApJ...886...42Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/886/42CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/259 : 6dF galaxy survey final redshift release (Jones+, 2009)J/ApJS/98/477 : Optical spectral atlas of Seyfert nuclei (Ho+ 1995)J/ApJS/115/185 : 3C 390.3 BVRI and H photometry (Dietrich+, 1998)J/A+A/369/57 : Monitoring Mkn 279 in BVRI & H{beta} (Santos-Lleo+, 2001)J/ApJ/613/682 : AGN masses & broad-line region sizes (Peterson+, 2004)J/ApJS/164/81 : Spectrophotometry of nearby galaxies (Moustakas+, 2006)J/ApJ/667/131 : Mass function of active black holes (Greene+, 2007)J/ApJ/683/L115 : Intermediate-line region in quasars (Hu+, 2008)J/ApJ/687/78 : FeII emission in quasars (Hu+, 2008)J/ApJS/194/45 : QSO properties from SDSS-DR7 (Shen+, 2011)J/ApJ/755/60 : Reverberation mapping for 5 Seyfert 1 galaxies (Grier+, 2012)J/MNRAS/431/836 : Type 1 AGN at low z.
