GLOW. II. A Census of Oxygen in Low-mass Galaxies*

Abstract 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 abundance and distribution. The Galaxies Losing Oxygen via Winds project quantifies the producti...

Radial Stellar Age Gradients in 42 Local Volume Dwarf Galaxies

Abstract We present radial stellar age gradients measured from star formation histories (SFHs) fit to resolved color–magnitude diagrams (CMDs) of 42 Local Volume dwarfs (6 ≲ Log M ⋆ / M ⊙ ≲ 9), spatially divided into elliptical annuli. Ages in each annulus are quantified using τ...
