Abstract
We combine our dynamical modeling black-hole mass measurements from the Lick AGN Monitoring Project 2016 sample with measured cross-correlation time lags and line widths to recover individual scale factors, f, used in traditional reverberation-mapping analyses. We extend our sample by including prior results from Code for AGN Reverberation and Modeling of Emission Lines (caramel) studies that have utilized our methods. Aiming to improve the precision of black-hole mass estimates, as well as uncover any regularities in the behavior of the broad-line region (BLR), we search for correlations between f and other AGN/BLR parameters. We find (i) evidence for a correlation between the virial coefficient and black-hole mass, (ii) marginal evidence for a similar correlation between and black-hole mass, (iii) marginal evidence for an anticorrelation of BLR disk thickness with and , and (iv) marginal evidence for an anticorrelation of inclination angle with , , and . Last, we find marginal evidence for a correlation between line-profile shape, when using the root-mean-square spectrum, , and the virial coefficient, , and investigate how BLR properties might be related to line-profile shape using caramel models.
