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…
Willman 1 Revisited: The Kinematics, Chemistry, and Orbital Properties of a Potentially-Disrupting Dwarf Galaxy
Camille Chiu, Marla Geha, William Cerny +4
The ultra-faint Milky Way satellite Willman 1 (W1; ; pc) was the first stellar over-density found via resolved stars in the Sloan Digital Sky Surv…
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…
The JWST Resolved Stellar Populations Early Release Science Program. VIII. The Spatially Resolved Star Formation History of WLM
Roger E. Cohen, Kristen B. W. McQuinn, Alessandro Savino +17
We measure radial stellar age gradients in the relatively isolated gas-rich dwarf irregular WLM, combining JWST NIRCam and NIRISS imaging with six archival Hubble fields over semi-…
