    The age-chemical abundance structure of the Galactic disc - II. α-dichotomy and thick disc formation
    We extend our previous work on the age-chemical abundance structure of the Galactic outer disc to the inner disc (4 < r < 8 kpc) based on the SDSS/APOGEE survey...

    The age-chemical abundance structure of the Galaxy I: evidence for a late-accretion event in the outer disc at z ∼ 0.6
    We investigate the age-chemical abundance structure of the outer Galactic disc at a galactocentric distance of r > 10 kpc as recently revealed by the SDSS...

    The age-metallicity relationship in the Fornax spheroidal dwarf galaxy
    We produce a comprehensive field star age-metallicity relationship (AMR) from the earliest epoch until ˜1 Gyr ago for three fields in the Fornax dwarf...

    The Apache Point Observatory Galactic Evolution Experiment (APOGEE)
    The Apache Point Observatory Galactic Evolution Experiment (APOGEE), one of the programs in the Sloan Digital Sky Survey III (SDSS-III), has now completed its...

    The APOGEE Data Release 16 Spectral Line List
    The updated H-band spectral-line list (from λ15000-17000) adopted by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) for the SDSS-IV Data...
  • Publication
    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 APOGEE Red-clump Catalog: Precise Distances, Velocities, and High-resolution Elemental Abundances over a Large Area of the Milky Way's Disk
    The Sloan Digital Sky Survey III's Apache Point Observatory Galactic Evolution Experiment (APOGEE) is a high-resolution near-infrared spectroscopic survey...

    The APOGEE Spectroscopic Survey of Kepler Planet Hosts: Feasibility, Efficiency, and First Results
    The Kepler mission has yielded a large number of planet candidates from among the Kepler Objects of Interest (KOIs), but spectroscopic follow-up of these...
  • Publication
    The APOGEE-2 Survey of the Orion Star-forming Complex. II. Six-dimensional Structure
    We present an analysis of spectroscopic and astrometric data from APOGEE-2 and Gaia DR2 to identify structures toward the Orion Complex. By applying a...
