APOGEE Chemical Abundances of Globular Cluster Giants in the Inner Galaxy
Ricardo P. Schiavon, Jennifer A. Johnson, Peter M. Frinchaboy +27
We report chemical abundances obtained by SDSS-III/APOGEE for giant stars in five globular clusters located within 2.2 kpc of the Galactic centre. We detect the presence of multipl…
Two Groups of Red Giants with Distinct Chemical Abundances in the Bulge Globular Cluster NGC 6553 Through the Eyes of APOGEE
Baitian Tang, Roger E. Cohen, Doug Geisler +18
Multiple populations revealed in globular clusters (GCs) are important windows to the formation and evolution of these stellar systems. The metal-rich GCs in the Galactic bulge are…
Warm Ionized Medium Throughout the Sagittarius-Carina Arm
Dhanesh Krishnarao, L. Matthew Haffner, Robert A. Benjamin +2
Wisconsin H-Alpha Mapper (WHAM) observations of H-Alpha and [S II] emission are used to trace the vertical distribution and physical conditions of the warm ionized med…
The Thirteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-IV Survey MApping Nearby Galaxies at Apache Point Observatory
SDSS Collaboration, Franco D. Albareti, Carlos Allende Prieto +335
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) began observations in July 2014. It pursues three core programs: APOGEE-2, MaNGA, and eBOSS. In addition, eBOSS cont…
Chemical tagging with APOGEE: Discovery of a large population of N-rich stars in the inner Galaxy
Ricardo P. Schiavon, Olga Zamora, Ricardo Carrera +42
Formation of globular clusters (GCs), the Galactic bulge, or galaxy bulges in general, are important unsolved problems in Galactic astronomy. Homogeneous infrared observations of l…
Cosmic variance in [O/Fe] in the Galactic disk
S. Bertran de Lis, C. Allende Prieto, S. R. Majewski +11
We examine the distribution of the [O/Fe] abundance ratio in stars across the Galactic disk using H-band spectra from the Apache Point Galactic Evolution Experiment (APOGEE). We mi…
