The Host Galaxies of Active Galactic Nuclei with Direct Black Hole Mass Measurements
Vardha N. Bennert, Nico Winkel, Tommaso Treu +13
Reverberation mapping (RM) determines the mass of black holes (BH) in active galactic nuclei (AGNs) by resolving the BH gravitational sphere of influence in the time domain. Recent…

Departures from Standard Disk Predictions in Intensive Ground-Based Monitoring of Three AGN
Diego Gonzalez-Buitrago, Aaron J. Barth, Rick Edelson +42
We present ground-based, multi-band light curves of the AGN Mrk~509, NGC\,4151, and NGC\,4593 obtained contemporaneously with \sw\, monitoring. We measure cross-correlation lags re…

Seoul National University AGN Monitoring Project. V. Velocity-resolved H-beta Reverberation Mapping and Evidence of Kinematics Evolution
Shu Wang, Jong-Hak Woo, Aaron J. Barth +13
We present velocity-resolved reverberation lags of H-beta for 20 active galactic nuclei (AGNs) from the Seoul National University AGN Monitoring Project. We detect unambiguous velo…
