Active Dwarf Galaxy Database II: Connections between Host Galaxy Properties and Black Hole Accretion Signatures
Erik J. Wasleske, Vivienne F. Baldassare, Christopher M. Carroll
We investigate the connection between accretion signatures and host galaxy properties in the context of how active dwarf galaxies are identified. We use the database constructed in…
Central Massive Black Holes Are Not Ubiquitous in Local Low-Mass Galaxies
Fan Zou, Elena Gallo, Anil C. Seth +13
The black-hole occupation fraction () defines the fraction of galaxies that harbor central massive black holes (MBHs), irrespective of their accretion activity leve…
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 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…
A Large-Scale Search for Photometrically Variable AGNs in Dwarf Galaxies Using the Young Supernova Experiment
Alexander Messick, Vivienne Baldassare, David O. Jones +12
We conduct an analysis of over 60,000 dwarf galaxies (7<=log(M_*/M_\odot)<=10) in search of photometric variability indicative of active galactic nuclei (AGNs). Using data from the…
AT 2020nov: Evidence for Disk Reprocessing in a Rare Tidal Disruption Event
Nicholas Earl, K. Decker French, Enrico Ramirez-Ruiz +23
We present a detailed analysis of AT 2020nov, a tidal disruption event (TDE) in the center of its host galaxy, located at a redshift of . AT 2020nov exhibits unique feat…
