TL;DR: In this article, a reanalysis of broad emission-line reverberation-mapping data was carried out for 35 active galactic nuclei (AGNs) based on a complete and consistent reanalysis, and it was shown that the highest precision measure of the virial product cτΔV2/G is obtained by using the cross-correlation function centroid (cf.
Journal ArticleDOI
Central Masses and Broad-Line Region Sizes of Active Galactic Nuclei. I. Comparing the Photoionization and Reverberation Techniques
TL;DR: In this article, the mass and emission-line region sizes of active galactic nuclei (AGNs) can be measured by "reverberation-mapping" techniques, and these results can be used to calibrate similar determinations made by photoionization models of the AGN line-emitting regions.
Journal ArticleDOI
Supermassive black holes in active galactic nuclei. II. Calibration of the black hole mass-velocity dispersion relationship for active galactic nuclei
Christopher A. Onken,Laura Ferrarese,David Merritt,David Merritt,Bradley M. Peterson,Richard W. Pogge,Marianne Vestergaard,Marianne Vestergaard,Amri Wandel +8 more
TL;DR: In this article, the authors calibrate reverberation-based black hole (BH) masses in active galactic nuclei (AGNs) by using the correlation between BH mass, MBH, and bulge/spheroid stellar velocity dispersion.
Journal ArticleDOI
Supermassive Black Holes in Active Galactic Nuclei. II. Calibration of the M-sigma Relationship for AGNs
Christopher A. Onken,Laura Ferrarese,David Merritt,Bradley M. Peterson,Richard W. Pogge,Marianne Vestergaard,Amri Wandel +6 more
TL;DR: In this article, the authors calibrate reverberation-based black hole masses in active galactic nuclei (AGNs) by using the correlation between black hole mass, M, and bulge/spheroid stellar velocity dispersion, sigma.
Journal ArticleDOI
Keplerian Motion of Broad-Line Region Gas as Evidence for Supermassive Black Holes in Active Galactic Nuclei
TL;DR: In this article, the authors used the time-delayed response of the emission lines to continuum variations to infer the size of the line-emitting region, and these determinations were combined with measurements of the Doppler widths of the variable line components to estimate a virial mass.
