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…
The DREAMS Project: Disentangling the Impact of Halo-to-Halo Variance and Baryonic Feedback on Milky Way Dark Matter Density Profiles
Alex M. Garcia, Jonah C. Rose, Paul Torrey +23
In this work, we utilize a new suite of Milky Way-mass halos from the DREAMS Project, simulated with Cold Dark Matter (CDM), to quantify the influence of baryon feedback and intrin…
The DREAMS Project: Disentangling the Impact of Halo-to-Halo Variance and Baryonic Feedback on Milky Way Satellite Galaxies
Jonah C. Rose, Mariangela Lisanti, Paul Torrey +24
We analyze the properties of satellite galaxies around 1,024 Milky Way-mass hosts from the DREAMS Project, simulated within a CDM cosmology. Utilizing the TNG galaxy-formation m…
The DREAMS Project: A New Suite of 1,024 Simulations to Contextualize the Milky Way and Assess Physics Uncertainties
Jonah C. Rose, Mariangela Lisanti, Paul Torrey +17
We introduce a new suite of 1,024 cosmological and hydrodynamical zoom-in simulations of Milky Way-mass halos, run with Cold Dark Matter, as part of the DREAMS Project. Each simula…
The abundance and properties of the lowest luminosity dwarf galaxies around the Milky Way: Insights from Semi-Analytic Models
Niusha Ahvazi, Andrew B. Pace, Christopher T. Garling +11
We investigate the formation and observable properties of faint satellite galaxies (M$_\rm V > -3$) in Milky Way-like halos using the semi-analytic galaxy formation model Galacticu…
The Proper Motion of Draco II with HST using Multiple Reference Frames and Methodologies
Jack T. Warfield, Kevin A. McKinnon, Sangmo Tony Sohn +13
We present proper motion (PM) measurements for Draco II, an ultra-faint dwarf satellite of the Milky Way. These PMs are measured using two epochs of Hubble Space Telescope Advanced…
A Unified Framework Connecting Chemical Enrichment to Resolved Star Formation Histories with Applications to Local Group Dwarf Irregulars
Christopher T. Garling, Alex M. Garcia, Niusha Ahvazi +4
We present a new framework for modeling the chemical enrichment histories of galaxies by integrating chemical evolution with resolved star formation histories (SFHs) derived from c…
Signatures of BH seeding on the relation: Predictions from the BRAHMA simulations
Jonathan Kho, Aklant K. Bhowmick, Paul Torrey +4
The James Webb Space Telescope (JWST) has identified a large population of supermassive (-) black holes (BHs) in the early universe (-). C…
How Many Bursts Does it Take to Form a Core at the Center of a Galaxy?
Olivia Mostow, Paul Torrey, Jonah C. Rose +4
We present a novel method for systematically assessing the impact of central potential fluctuations associated with bursty outflows on the structure of dark matter halos for classi…
Star formation beyond galaxies: widespread in-situ formation of intra-cluster stars
Niusha Ahvazi, Laura V. Sales, Julio F. Navarro +3
We study the fraction of the intra-cluster light (ICL) formed in-situ in the three most massive clusters of the TNG50 simulation, with virial masses M. We…
The progenitors of the intra-cluster light and intra-cluster globular clusters in galaxy groups and clusters
Niusha Ahvazi, Laura V. Sales, Jessica E. Doppel +3
We use the IllustrisTNG50 cosmological hydrodynamical simulation, complemented by a catalog of tagged globular clusters, to investigate the properties and build up of two extended…
A comprehensive model for the formation and evolution of the faintest Milky Way dwarf satellites
Niusha Ahvazi, Andrew Benson, Laura V. Sales +4
In this study, we modify the semi-analytic model Galacticus in order to accurately reproduce the observed properties of dwarf galaxies in the Milky Way. We find that reproducing ob…
