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…
Homogeneous Analysis of Globular Clusters from the APOGEE Survey with the BACCHUS Code III. Cen
Szabolcs Mészáros, Thomas Masseron, José G. Fernández-Trincado +18
We study the multiple populations of Cen by using the abundances of Fe, C, N, O, Mg, Al, Si, K, Ca, and Ce from the high-resolution, high signal-to-noise (S/N70) spectra of…
The Stars of the HETDEX Survey. I. Radial Velocities and Metal-Poor Stars from Low-Resolution Stellar Spectra
Keith Hawkins, Greg Zeimann, Chris Sneden +18
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is an unbiased, massively multiplexed spectroscopic survey, designed to measure the expansion history of the universe thr…
