We present the first ever models of a broad line region (BLR) at the peak of active galactic nucleus (AGN) activity using the multiply imaged z = 2.805 quasar SDSS J2222+2745. The modeled data consist of monthly spectra covering the broad C iv emission line over a 5.3 yr baseline. The models suggest a thick disk BLR that is inclined by ∼40° to the observer’s line of sight and with an emissivity weighted median radius of rmedian=33.0−2.1+2.4 light days. The kinematics are dominated by near… 
Spectroastrometry and Reverberation Mapping: The Mass and Geometric Distance of the Supermassive Black Hole in the Quasar 3C 273
The quasar 3C 273 has been observed with infrared spectroastrometry (SA) of the broad Paα line and optical reverberation mapping (RM) of the broad Hβ line. SA delivers information about the angular
The Broad Line Region and Black Hole Mass of NGC 4151
We present a reanalysis of reverberation mapping data from 2005 for the Seyfert galaxy NGC 4151, supplemented with additional data from the literature to constrain the continuum variations over a
Hα Reverberation Mapping of the Intermediate-mass Active Galactic Nucleus in NGC 4395
We present the results of a high-cadence spectroscopic and imaging monitoring campaign of the active galactic nucleus (AGN) of NGC 4395. High signal-to-noise-ratio spectra were obtained at the
