    Chemical Cartography with APOGEE: Mapping Disk Populations with a 2-process Model and Residual Abundances

    We apply a novel statistical analysis to measurements of 16 elemental abundances in 34,410 Milky Way disk stars from the final data release (DR17) of APOGEE-2...

    Chemical Evolution in the Milky Way: Rotation-based Ages for APOGEE-Kepler Cool Dwarf Stars

    We use models of stellar angular momentum evolution to determine ages for ∼500 stars in the APOGEE-Kepler Cool Dwarfs sample. We focus on lower-main-sequence...

    Evolution of the Mass-Metallicity Relation from Redshift z ≈ 8 to the Local Universe

    A tight positive correlation between the stellar mass and the gas-phase metallicity of galaxies has been observed at low redshifts. The redshift evolution of...

    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...

    Recovering Age-Metallicity Distributions from Integrated Spectra: Validation with MUSE Data of a Nearby Nuclear Star Cluster

    Current instruments and spectral analysis programs are now able to decompose the integrated spectrum of a stellar system into distributions of ages and...

    The APOGEE Library of Infrared SSP Templates (A-LIST): High-resolution Simple Stellar Population Spectral Models in the H Band

    Integrated light spectroscopy from galaxies can be used to study the stellar populations that cannot be resolved into individual stars. This analysis relies on...

    The Mass-Metallicity Relation at z 1-2 and Its Dependence on the Star Formation Rate

    We present a new measurement of the gas-phase mass-metallicity relation (MZR) and its dependence on star formation rates (SFRs) at 1.3 < z < 2.3. Our sample...
