The GALAH+ Survey: Third Data Release

Sven Buder, Sanjib Sharma, Janez Kos +44

The ensemble of chemical element abundance measurements for stars, along with precision distances and orbit properties, provides high-dimensional data to study the evolution of the…

The Similarity of Abundance Ratio Trends and Nucleosynthetic Patterns in the Milky Way Disk and Bulge

Emily Griffith, David H. Weinberg, Jennifer A. Johnson +9

We compare abundance ratio trends in a sample of Milky Way bulge stars ( kpc) from the Apache Point Observatory Galactic Evolution Experiment (APOGEE)…

Exploring the stellar age distribution of the Milky Way Bulge using APOGEE

Sten Hasselquist, Gail Zasowski, Diane K. Feuillet +20

We present stellar age distributions of the Milky Way (MW) bulge region using ages for 6,000 high-luminosity (), metal-rich () bulge stars…

The contribution of N-rich stars to the Galactic stellar halo using APOGEE red giants

Danny Horta, J. Ted Mackereth, Ricardo P. Schiavon +13

The contribution of dissolved globular clusters (GCs) to the stellar content of the Galactic halo is a key constraint on models for GC formation and destruction, and the mass assem…

The Milky Way's bulge star formation history as constrained from its bimodal chemical abundance distribution

Jianhui Lian, Gail Zasowski, Sten Hasselquist +9

We conduct a quantitative analysis of the star formation history (SFH) of the Milky Way's bulge by exploiting the constraining power of its stellar [Fe/H] and [Mg/Fe] distribution…

The Magellanic Edges Survey I. Description and First Results

L. R. Cullinane, A. D. Mackey, G. S. Da Costa +6

We present an overview of, and first science results from, the Magellanic Edges Survey (MagES), an ongoing spectroscopic survey mapping the kinematics of red clump and red giant br…

Evidence from APOGEE for the presence of a major building block of the halo buried in the inner Galaxy

Danny Horta, Ricardo P. Schiavon, J. Ted Mackereth +13

We report evidence from APOGEE for the presence of a new metal-poor stellar structure located within 4~kpc of the Galactic centre. Characterised by a chemical composition res…

On the Color-Metallicity Relation of the Red Clump and the Reddening Toward the Magellanic Clouds

David M. Nataf, Santi Cassisi, Luca Casagrande +2

The zero point of the reddening toward the Large Magellanic Cloud (LMC) has been the subject of some dispute. Its uncertainty propagates as a systematic error for methods which mea…

The Predicted Properties of Helium-Enriched Globular Cluster Progenitors at High Redshift

David M. Nataf, Shunsaku Horiuchi, Guglielmo Costa +5

Globular cluster progenitors may have been detected by \textit{HST}, and are predicted to be observable with \textit{JWST} and ground-based extremely-large telescopes with adaptive…

The Bulge Radial Velocity Assay for RR Lyrae stars (BRAVA-RR) DR2: a Bimodal Bulge?

Andrea Kunder, Angeles Perez-Villegas, R. Michael Rich +11

Radial velocities of 2768 fundamental mode RR Lyrae stars (RRLs) toward the Southern Galactic bulge are presented, spanning the southern bulge from -8 < l < +8 and -3 < b <-6. Dist…

Fundamental relations for the velocity dispersion of stars in the Milky Way

Sanjib Sharma, Michael R. Hayden, Joss Bland-Hawthorn +34

We explore the fundamental relations governing the radial and vertical velocity dispersions of stars in the Milky Way, from combined studies of complementary surveys including GALA…

The Chemical Compositions of Accreted and {\it in situ} Galactic Globular Clusters According to SDSS/APOGEE

Danny Horta, Ricardo P. Schiavon, J. Ted Mackereth +16

Studies of the kinematics and chemical compositions of Galactic globular clusters (GCs) enable the reconstruction of the history of star formation, chemical evolution, and mass ass…
