The Apache Point Observatory extra-Galactic Evolution Experiment (APOeGEE): Chemical Abundance Trends for Seven Dwarf Spheroidal Galaxies in the APOGEE Survey

Matthew Shetrone, Rachael L. Beaton, Christian R. Hayes +10

In addition to comprehensive surveys of the Milky Way bulge, disk, and halo, the Apache Point Galactic Evolution Experiment (APOGEE) project observed seven dwarf spheroidal satelli…

CAPOS: The bulge Cluster APOgee Survey VIII. Final ASPCAP results for all clusters

Doug Geisler, Cesar Muñoz, Sandro Villanova +12

Bulge globular clusters(BGCs) are exceptional tracers of the formation and chemodynamical evolution of this oldest Galactic component. However, until now, observational difficultie…

Tracing Red Giant Members of the Globular Cluster Palomar 5 with APOGEE and Gaia

Allyson A. Sheffield, Sarah Pearson, Lenin F. Nolasco +5

The globular cluster Palomar 5 (Pal 5) is in the process of being tidally shredded as it orbits the Milky Way. Its core is currently at a heliocentric distance of ~21 kpc, near apo…

Tidal Debris Candidates from the Centauri Accretion Event and its Role in Building Up the Milky Way Halo

Borja Anguiano, Arik Mitschang, Takanobu Kirihara +11

We identify stellar tidal debris from the Centauri ( Cen) system among field stars in the APOGEE survey via chemical tagging using a neural network trained on APOGEE obser…

Chemical tagging with APOGEE, MUSE, and HST: constraints on the formation of Centauri

Andrew C. Mason, Ricardo P. Schiavon, Sebastian Kamann +9

A plethora of evidence suggests that Centauri ( Cen) is the nuclear star cluster of a galaxy that merged with the Milky Way in early times. We use APOGEE, Gaia, MUSE, and…
