From starlight to dark matter: a stochastic interpolation approach to map dark matter from stellar density

Xiaowei Ou, Lina Necib, Carolina Cuesta-Lazaro +9

The dark matter halo profile in galaxies holds key information about the nature of dark matter and galaxy formation. Constraining the dark matter profile of galaxies beyond the Mil…

From observing strategies to velocity dispersion bias: forward modeling unresolved binaries in ultra-faint dwarf galaxies

Xiaowei Ou, Andrew B. Pace, Nitya Kallivayalil +9

Ultra-faint dwarf galaxies (UFDs) in the Milky Way are ideal probes of low-mass galaxy formation and dark matter because they are highly dark-matter dominated. In the lowest-mass s…

Learning the Universe at High Redshifts: Impact of Accretion Modeling on Early Black Hole Growth

Jonathan Kho, Aklant K. Bhowmick, Rainer Weinberger +8

JWST discoveries of the earliest () supermassive black holes (BHs, ) challenge the BH seeding and accretion models of most cosmol…

Hubble Astrometry for the Local Group and Beyond in the 2030s

S. Tony Sohn, Paul Bennet, Kevin Andrew McKinnon +23

Hubble's long, stable astrometric baseline creates a rare opportunity for discovery in the Local Group and beyond. Many nearby galaxies, streams, and star clusters already have arc…

The Curious Case of Centaurus A: On the Subject of the Quenched satellites

Sachi Weerasooriya, Mia Sauda Bovill, Matthew A. Taylor +6

The satellite system of Centaurus A presents a curious cosmological puzzle: while the global population is consistent with theoretical expectations, its inner regions (d<150 kpc) e…

Testing warm dark matter with kinematics of the smallest galaxies

M. Sten Delos, Niusha Ahvazi, Andrew Benson

Every dark matter halo forms with a density cusp at its center. For warm dark matter (WDM), these prompt cusps can be massive enough to influence the kinematics…
