Can BLR line profile shape improve single-epoch black hole mass estimates?

Lizvette Villafaña, Tommaso Treu, Shu Wang +7

The virial coefficient (), which is meant to encapsulate broad-line region (BLR) geometry and kinematics, remains one of the largest sources of systematic uncertainty in black h…

Cepheid-based Distances to NGC 4303 and NGC 1068

Madison Markham, Misty C. Bentz, Laura Ferrarese +2

We present Cepheid-based distances to two canonical AGN: NGC 4303 (M 61) and NGC 1068. Data were obtained using the Hubble Space Telescope with nonredundant time spacing over 12 vi…

JWST Observations of the Double Nucleus in NGC 4486B: Possible Evidence for a Recent Binary SMBH Merger and Recoil

Behzad Tahmasebzadeh, Monica Valluri, Shashank Dattathri +19

A recent study of the compact elliptical galaxy NGC 4486B using JWST-NIRSpec IFU kinematics confirmed a supermassive black hole (SMBH) of mass (~8% of…

Continuum Reverberation Mapping of 18 AGN Over Four Years

Jake A. Miller, Edward M. Cackett, Misty C. Bentz +3

Continuum reverberation mapping probes the size scale of the optical continuum-emitting region in active galactic nuclei (AGN). The source of this emission has long been thought to…

A Stellar Dynamical Mass for the Central Black Hole in MCG06-30-15

Nabanita Das, Misty C. Bentz, Eugene Vasiliev +4

We present the stellar dynamical mass of the central black hole in the nearby Seyfert galaxy MCG06-30-15 using the Schwarzschild orbit-superposition method implemented in the op…

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…
