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…
Picture an Astronomer: Best Practices for Retaining Talent in Astrophysics
Ava Polzin, Katherine E. Whitaker, C. Megan Urry +85
Women are consistently underrepresented in astrophysics yet are simultaneously subject to disproportionate attrition at every career stage. This disparity between demonstrated effi…
What Sets the Metallicity of Ultra-Faint Dwarfs?
Vance Wheeler, Andrey Kravtsov, Anirudh Chiti +2
We use intergalactic medium (IGM) metallicity distributions from several state-of-the-art cosmological simulations of Milky Way analogs and a semi-analytic model of ultra-faint dwa…
On the universality of star formation efficiency in galaxies
Ava Polzin, Andrey V. Kravtsov, Vadim A. Semenov +1
We analyze high-resolution hydrodynamics simulations of an isolated disk dwarf galaxy with an explicit model for unresolved turbulence and turbulence-based star formation prescript…
