A Detailed View of the Broad Line Region in NGC 3783 from Velocity-Resolved Reverberation Mapping
Misty C. Bentz, Peter R. Williams, Rachel Street +3
We have modeled the full velocity-resolved reverberation response of the H and He II optical broad emission lines in NGC 3783 to constrain the geometry and kinematics of the low…
Dynamical Modeling of the CIV Broad Line Region of the Multiply Imaged Quasar SDSS J2222+2745
Peter R. Williams, Tommaso Treu, Håkon Dahle +8
We present CIV BLR modeling results for the multiply imaged quasar SDSS J2222+2745. Using data covering a 5.3 year baseline after accounting for gravitational time delays…
The black hole mass of the multiply imaged quasar SDSS J2222+2745 from velocity-resolved time lags of the CIV emission line
Peter R. Williams, Tommaso Treu, Håkon Dahle +6
We present the first results of a 4.5 year monitoring campaign of the three bright images of multiply imaged quasar SDSS J2222+2745 using the Gemini North Multi-Object Sp…
High-resolution imaging follow-up of doubly imaged quasars
Anowar J. Shajib, Eden Molina, Adriano Agnello +8
We report upon three years of follow-up and confirmation of doubly imaged quasar lenses through imaging campaigns from 2016-2018 with the Near-Infrared Camera2 (NIRC2) on the W. M.…
Modelling the AGN broad line region using single-epoch spectra II. Nearby AGN
S. I. Raimundo, M. Vestergaard, M. R. Goad +4
The structure of the broad line region (BLR) is an essential ingredient in the determination of active galactic nuclei (AGN) virial black hole masses, which in turn are important t…
The Lick AGN Monitoring Project 2011: Dynamical Modeling of the Broad-Line Region
Peter R. Williams, Anna Pancoast, Tommaso Treu +22
We present models of the H-emitting broad-line region (BLR) in seven Seyfert 1 galaxies from the Lick AGN (Active Galactic Nucleus) Monitoring Project 2011 sample, drawing infer…
