Hidden in the Halo: New Diffuse Star Clusters in the M82 Starburst with JWST

Deepthi S. Prabhu, David J. Sand, Burcin Mutlu-Pakdil +12

Diffuse star clusters (DSCs) occupy a poorly explored region of the size-luminosity plane between classical globular clusters (GCs) and dwarf galaxies. Here we report the discovery…

Discovery, Characterization, and Potential Origins of a Stream in the Stellar Halo of Nearby LMC-Mass Galaxy NGC 55

Benjamin N. Velguth, Burçin Mutlu-Pakdil, Erik Tollerud +33

We present a previously undetected stellar stream in the halo of the LMC-mass dwarf galaxy NGC 55 (2 Mpc), as part of an ongoing effort to characterize the stellar halos of LMC/SMC…

GLOW II: A Census of Oxygen in Low-Mass Galaxies

Kristen B. W. McQuinn, O. Grace Telford, Andrey V. Kravtsov +12

Oxygen is forged by stars and redistributed through galaxies by feedback-driven outflows, leaving a record of star formation and the baryon cycle imprinted on its present-day abund…

Radial Stellar Age Gradients in 42 Local Volume Dwarf Galaxies

Roger E. Cohen, Kristen B. W. McQuinn, O. Grace Telford +4

We present radial stellar age gradients measured from star formation histories (SFHs) fit to resolved color-magnitude diagrams (CMDs) of 42 Local Volume dwarfs (6Log M$_{…

GLOW I: Comprehensive Measurements of Gas-Rich, Star-Forming, Low-Mass Galaxies in the Nearby Universe

Kristen B. W. McQuinn, O. Grace Telford, Roger Cohen +12

Gas-rich, star-forming, low-mass galaxies in the nearby universe are powerful laboratories for studying baryonic physics in detail including: stellar mass assembly, stellar feedbac…

Deep Imaging of Grus II and Horologium II: Structure and Extent of Two Ultra-Faint Milky Way Satellites

Deepthi S. Prabhu, David J. Sand, Anirudh Chiti +29

We present deep, wide-field Magellan/Megacam imaging of the ultra-faint Milky Way (MW) satellites Grus II (Gru II) and Horologium II (Hor II), with the aim of deriving improved con…

ID-MAGE II: The Star Forming Satellites of Low-Mass Hosts

Laura Congreve Hunter, Burçin Mutlu-Pakdil, Michael B. Farnell +14

We present results from our ongoing campaign to follow up the satellite candidates from the Identifying Dwarfs of MC Analog GalaxiEs (ID-MAGE) survey. Previously, we published a li…
