Aligning Retrograde Nuclear Cluster Orbits with an Active Galactic Nucleus Accretion Disc
Syeda S. Nasim, Gaia Fabj, Freddy Caban +6
Stars and stellar remnants orbiting a supermassive black hole (SMBH) can interact with an active galactic nucleus (AGN) disc. Over time, prograde orbiters (inclination $i<90^{\circ…
Dwarf AGNs from Variability for the Origins of Seeds (DAVOS): Intermediate-mass black hole demographics from optical synoptic surveys
Colin J. Burke, Yue Shen, Xin Liu +4
We present a phenomenological forward Monte Carlo model for forecasting the population of active galactic nuclei (AGNs) in dwarf galaxies observable via their optical variability.…
RESOLVE and ECO: Finding Low-Metallicity Dwarf AGN Candidates Using Optimized Emission-Line Diagnostics
Mugdha S. Polimera, Sheila J. Kannappan, Chris T. Richardson +6
Existing star-forming vs. active galactic nucleus (AGN) classification schemes using optical emission-line diagnostics mostly fail for low-metallicity and/or highly star-forming ga…
A hidden population of massive black holes in simulated dwarf galaxies
Ray S. Sharma, Alyson M. Brooks, Michael Tremmel +3
We explore the characteristics of actively accreting MBHs within dwarf galaxies in the \textsc{Romulus25} cosmological hydrodynamic simulation. We examine the MBH occupation fracti…
Optical and JWST Mid-IR Emission Line Diagnostics for Simultaneous IMBH and Stellar Excitation in z~0 Dwarf Galaxies
C. T. Richardson, C. Simpson, M. S. Polimera +4
Current observational facilities have yet to conclusively detect intermediate mass black holes (IMBHs) that fill in the evolutionary gap between early unive…
