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…
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…
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…
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 Supermassive Black Hole in a Diminutive Ultra-compact Dwarf Galaxy Discovered with JWST/NIRSpec+IFU
Matthew A. Taylor, Behzad Tahmasebzadeh, Solveig Thompson +18
The integral-field unit mode of the Near-Infrared Spectrograph (NIRSpec+IFU) mounted on the James Webb Space Telescope has now enabled kinematic studies of smaller and less massive…
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…
