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 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…
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…
Building a Roadmap for Hubble science into the 2030s: Crucial UV spectroscopy of Oe stars in nearby galaxies
A. Wofford, D. Pauli, A. A. C. Sander +12
Hubble's unique COS G130M+G160M and STIS E140M UV spectral capabilities are essential for characterizing and understanding fundamental properties of main-sequence O-type emission-l…
The First Empirical Calibration of the MIR Abundance Diagnostic Ne with JWST
Noah S. J. Rogers, Evan D. Skillman, Danielle A. Berg +10
Large surveys of galaxies in the local and high-redshift Universe have, traditionally, relied on the intensity of rest-optical emission lines from metal ions in the Interstellar Me…
JWST Captures Growth of Aromatic Hydrocarbon Dust Particles in the Extremely Metal-poor Galaxy Sextans A
Elizabeth J. Tarantino, Julia Roman-Duval, Karin M. Sandstrom +16
The mid-infrared spectrum of star-forming, high metallicity galaxies is dominated by emission features from aromatic and aliphatic bonds in small carbonaceous dust grains, often re…
