APOGEE Chemical Abundance Patterns of the Massive Milky Way Satellites
Sten Hasselquist, Christian R. Hayes, Jianhui Lian +42
The SDSS-IV Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey has obtained high-resolution spectra for thousands of red giant stars distributed among the massi…
Final Targeting Strategy for the SDSS-IV APOGEE-2S Survey
Felipe A. Santana, Rachael L. Beaton, Kevin R. Covey +43
APOGEE is a high-resolution (R sim 22,000), near-infrared, multi-epoch, spectroscopic survey of the Milky Way. The second generation of the APOGEE project, APOGEE-2, includes an ex…
Final Targeting Strategy for the SDSS-IV APOGEE-2N Survey
Rachael L. Beaton, Ryan J. Oelkers, Christian R. Hayes +57
APOGEE-2 is a dual-hemisphere, near-infrared (NIR), spectroscopic survey with the goal of producing a chemo-dynamical mapping of the Milky Way Galaxy. The targeting for APOGEE-2 is…
Chemical Cartography with APOGEE: Mapping Disk Populations with a Two-Process Model and Residual Abundances
David H. Weinberg, Jon A. Holtzman, Jennifer A. Johnson +33
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. Building on recent w…
Constraining the Milky Way's Ultraviolet to Infrared SED with Gaussian Process Regression
Catherine E. Fielder, Jeffrey A. Newman, Brett H. Andrews +5
Improving our knowledge of global Milky Way (MW) properties is critical for connecting the detailed measurements only possible from within our Galaxy to our understanding of the br…
New families in our Solar neighborhood: applying Gaussian Mixture models for objective classification of structures in the Milky Way and in simulations
Farnik Nikakhtar, Robyn E. Sanderson, Andrew Wetzel +10
The standard picture of galaxy formation motivates the decomposition of the Milky Way into 3--4 stellar populations with distinct kinematic and elemental abundance distributions: t…
