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…

The Next Generation Virgo Cluster Survey (NGVS). XL. The Morphological Classification of Virgo Cluster Galaxies

Max M. Kurzner, Patrick Côté, Laura Ferrarese +19

We present a study of morphologies, based on deep imaging of the Virgo Cluster from the Next Generation Virgo Cluster Survey (NGVS), for 3689…

A JWST View of the Overmassive Black Hole in NGC 4486B

Behzad Tahmasebzadeh, Matthew A. Taylor, Monica Valluri +19

We present a new stellar dynamical measurement of the supermassive black hole (SMBH) in the compact elliptical galaxy NGC 4486B, based on integral field spectroscopy with JWST/NIRS…

The Next Generation Virgo Cluster Survey (NGVS). II. A Catalog of Galaxies in the Virgo Cluster

Laura Ferrarese, Patrick Cote, Lauren A. MacArthur +51

The Next Generation Virgo Cluster Survey (NGVS) is a deep, high resolution imaging campaign that used the 1 deg MegaCam instrument on the Canada-France-Hawaii Telescope to carr…

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…

The Lower Limit of Dynamical Black Hole Masses Detectable in Virgo Compact Stellar Systems Using the JWST/NIRSpec IFU

Behzad Tahmasebzadeh, Andrew Lapeer, Eugene Vasiliev +3

Due to observational challenges, the mass function of black holes (BH) at lower masses is poorly constrained in the local universe. Understanding the occupation fraction of BHs in…
