Scylla V: Constraints on the spatial and temporal distribution of bursts and the interaction history of the Magellanic Clouds from their resolved stellar populations

Clare Burhenne, Kristen B. W. McQuinn, Roger E. Cohen +9

We measure the star formation histories (SFHs) from the Scylla survey in approximately 98,000 pc^2 and 75,000 pc^2 of the SMC and LMC, respectively, using deep Hubble Space Telesco…

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…

Searching for Stellar-Feedback-Driven Outflow Signatures: A Deep Dive into NGC 3741

Lexi N. Gault, Liese van Zee, Elizabeth A. K. Adams +5

Stellar feedback drives winds and outflows critical to the baryon cycles of low-mass galaxies whose shallow gravitational potential wells make them particularly susceptible to mass…

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…

Wide binaries in an ultra-faint dwarf galaxy: discovery, population modeling, and a nail in the coffin of primordial black hole dark matter

Cheyanne Shariat, Kareem El-Badry, Mario Gennaro +24

We report the discovery and characterization of a wide binary population in the ultrafaint dwarf galaxy Boötes I using deep JWST/NIRCam imaging. Our sample consists of 52 candidate…

Observed Timescales of Stellar Feedback in Star-Forming, Low-Mass Galaxies

Laura C. Hunter, Liese van Zee, Roger E. Cohen +5

Understanding the timescales of atomic gas turbulence is crucial to understanding the interplay between star formation and the interstellar medium (ISM). To investigate the timesca…
