A Comprehensive AGN Inventory for the Dwarf-Dominated RESOLVE and ECO Surveys: Mass-Dependent AGN Types and Occupation Fractions

Mugdha S. Polimera, Sheila J. Kannappan, Chris T. Richardson +7

We catalog Active Galactic Nuclei (AGN) in the volume- and mass-limited RESOLVE and ECO surveys using (i) the BPT plot with standard and alternate demarcations, (ii) the BPT plot a…

Handy Relation Between Binary Black Hole Merger Times and Host Galaxy Properties

Kelly Holley-Bockelmann, Fazeel Khan, Isaiah Williams +6

Over the past 15 years, the evidence has clearly demonstrated that massive black hole (MBH) binary merger timescales depend strongly on the structural and kinematic properties of t…

Emission Line Diagnostics for IMBHs in Dwarf Galaxies: Accounting for BH Seeding and ULX Excitation

Chris T. Richardson, Jordan Wels, Kristen Garofali +13

Dwarf AGN serve as the ideal systems for identifying intermediate mass black holes (IMBHs) down to the most elusive regimes (). However, the ubiquitousl…

Little Red Dots are Tidal Disruption Events in Runaway-Collapsing Clusters

Jillian Bellovary

I hypothesize a physical explanation for the "Little Red Dots" (LRDs) discovered by the James Webb Space Telescope (JWST). The first star formation in the universe occurs in dense…

Intermediate Mass Ratio Inspirals in Milky Way Galaxies

Jillian Bellovary, Yuantong Luo, Thomas Quinn +3

A consequence of a non-zero occupation fraction of massive black holes (MBHs) in dwarf galaxies is that these MBHs can become residents of larger galaxy halos via hierarchical merg…

An Enhanced Massive Black Hole Occupation Fraction Predicted in Cluster Dwarf Galaxies

Michael Tremmel, Angelo Ricarte, Priyamvada Natarajan +3

The occupation fraction of massive black holes (MBHs) in dwarf galaxies offers interesting insights into initial black hole seeding mechanisms and their mass assembly history, thou…
