    Depolarizing Collisions with Hydrogen: Neutral and Singly Ionized Alkaline Earths
    Depolarizing collisions are elastic or quasielastic collisions that equalize the populations and destroy the coherence between the magnetic sublevels of atomic...

    DESI Emission-line Galaxies: Unveiling the Diversity of [O II] Profiles and Its Links to Star Formation and Morphology
    We study the [O II] profiles of emission-line galaxies (ELGs) from the Early Data Release of the Dark Energy Spectroscopic Instrument (DESI). To this end, we...

    Detailed Abundances in the Galactic Center: Evidence of a Metal-rich Alpha-enhanced Stellar Population
    We present a detailed study of the composition of 20 M giants in the Galactic center with 15 of them confirmed to be in the nuclear star cluster. As a control...

    Detailed Chemical Abundances for a Benchmark Sample of M Dwarfs from the APOGEE Survey
    Individual chemical abundances for 14 elements (C, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, and Ni) are derived for a sample of M dwarfs using high...

    Detailed Diagnostics of an X-Ray Flare in the Single Giant HR 9024
    We analyze a 96 ks Chandra HETGS observation of the single G-type giant HR 9024. The high flux allows us to examine spectral line and continuum diagnostics at...

    Detailed Theoretical Predictions for the Outskirts of Dark Matter Halos
    In the present work we describe the formalism necessary to derive the properties of dark matter halos beyond 2 virial radii using the spherical collapse model...
