The black hole occupation fraction of local dwarf galaxies with AXIS
Elena Gallo, Edmund Hodges-Kluck, Tommaso Treu +7
The fraction of local dwarf galaxies that hosts massive black holes is arguably the cleanest diagnostic of the dominant seed formation mechanism of today's supermassive black holes…
Intermediate-Mass Black Holes in Star Clusters and Dwarf Galaxies
Abbas Askar, Vivienne F. Baldassare, Mar Mezcua
Black holes (BHs) with masses between 100 to 100,000 times the mass of the Sun () are classified as intermediate-mass black holes (IMBHs), potentially representing…
The 50 Mpc Galaxy Catalog (50MGC): Consistent and Homogeneous Masses, Distances, Colors, and Morphologies
D. Ohlson, A. C. Seth, E. Gallo +2
We assemble a catalog of 15424 nearby galaxies within 50 Mpc with consistent and homogenized mass, distance, and morphological type measurements. Our catalog combines galaxies from…
X-ray Properties of Optically Variable Low-mass AGN Candidates
Alexander Messick, Vivienne Baldassare, Marla Geha +1
We present an X-ray analysis of fourteen nearby (z < 0.044) AGN in low mass galaxies (M_* <= 5*10^9 Msun) selected based on their optical variability (Baldassare et al. 2020). Comp…
X-ray Analysis of AGN from the GALEX Time Domain Survey
Erik J. Wasleske, Vivienne F. Baldassare
We analyze the X-ray properties for a sample of 23 high probability AGN candidates with ultraviolet variability identified in Wasleske et al. (2022). Using data from the Chandra X-…
The Merian Survey: Design, Construction, and Characterization of a Filter Set Optimized to Find Dwarf Galaxies and Measure their Dark Matter Halo Properties with Weak Lensing
Yifei Luo, Alexie Leauthaud, Jenny Greene +28
The Merian survey is mapping 850 degrees of the Hyper Suprime-Cam Strategic Survey Program (HSC-SSP) wide layer with two medium-band filters on the 4-meter Victor M. Bla…
Multiwavelength Scrutiny of X-ray Sources in Dwarf Galaxies: ULXs versus AGN
Erica Thygesen, Richard M. Plotkin, Roberto Soria +10
Owing to their quiet evolutionary histories, nearby dwarf galaxies (stellar masses ) have the potential to teach us about the mechanism(s) t…
