Characterizing the disruption of Böotes III: a missing link in the Galactic halo?
Jaclyn Jensen, Daniel A. Boyea, Alan W. McConnachie +14
The authors investigate whether the Boötes III dwarf galaxy is the source of the Styx stellar stream by searching for tidal debris with Gaia data, new CaHK imaging, and matched‑fil…
Magnesium isotope ratios in Milky Way and dwarf galaxy stars
M. McKenzie, S. Monty, D. Yong +8
The paper measures magnesium isotope ratios in stars from dwarf galaxies and the Milky Way, finding distinct patterns at fixed iron abundance but similar ratios at fixed magnesium…
Tidal Grinding of Dwarf Galaxies in Cluster Environments
Sanjaya Paudel, Suk-Jin Yoon, Tek Prasad Adhikari +4
The paper investigates how the shapes of dwarf elliptical galaxies in the Virgo cluster relate to their tidal histories, finding that flatter dwarfs are more uniformly distributed…
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
The paper introduces a framework that combines resolved star formation histories with chemical evolution models to trace the metallicity growth of dwarf galaxies, and applies it to…
JWST NIRCam and MIRI Reveal the Dust-Producing AGB Population of NGC 6822
Conor Nally, Olivia C. Jones, Laura LenkiÄ +9
The paper presents a JWST NIRCam and MIRI photometric catalogue of the dwarf galaxy NGC 6822, identifies dust‑producing asymptotic giant branch (AGB) stars, and quantifies their du…
