    About Metallicity Variations in the Local Galactic Interstellar Medium

    In this paper we discuss and confront recent results on metallicity variations in the local interstellar medium, obtained from observations of H II regions and...

    Evidence for the Accretion of Gas in Star-forming Galaxies: High N/O Abundances in Regions of Anomalously Low Metallicity

    While all models for the evolution of galaxies require the accretion of gas to sustain their growth via on-going star formation, it has proven difficult to...

    Local and Global Gas Metallicity versus Stellar Age Relation in MaNGA Galaxies

    The search for new global scaling relations linking the physical properties of galaxies has a fundamental interest. Furthermore, their recovery from spatially...

    Lyα Emitting Galaxies (LAEs) at Cosmic Dawn: Implications and Predictions

    The detection of Lyα emitting galaxies (LAEs) puts severe constraints on the reionization history. In this paper, we derive the properties of very high-z LAEs...

    Milky Way Satellite Census. IV. Constraints on Decaying Dark Matter from Observations of Milky Way Satellite Galaxies

    We use a recent census of the Milky Way (MW) satellite galaxy population to constrain the lifetime of particle dark matter (DM). We consider two-body decaying...

    The Lazy Giants: APOGEE Abundances Reveal Low Star Formation Efficiencies in the Magellanic Clouds

    We report the first APOGEE metallicities and α-element abundances measured for 3600 red giant stars spanning a large radial range of both the Large (LMC) and...
