Is Liller 1 a building block of the Galactic bulge? -- Evidence with APOGEE

Anna Liptrott, Ricardo P. Schiavon, Andrew C. Mason +10

Liller 1 is a stellar system orbiting within the inner 0.8kpc of the Galactic centre, characterised by a wide spread in age and metallicity, indicating a high mass. Liller 1 has be…

Measuring and modelling the Splash with APOGEE/Gaia and ARTEMIS

Shobhit Kisku, Ricardo P. Schiavon, Andreea S. Font +6

Using combined data from SDSS-IV/APOGEE and Gaia, we study the chemo-dynamical properties of the Splash population in comparison with those of the high-alpha disc. We investigate a…

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 observa…

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 HS…

Realistic simulated galaxies form [/Fe]-[Fe/H] knees due to a sustained decline in their star formation rates

Andrew C. Mason, Robert A. Crain, Ricardo P. Schiavon +5

We examine the stellar [/Fe]-[Fe/H] distribution of present-day galaxies in a high-resolution EAGLE simulation. A slight majority of galaxies exhibit the canonical…

The APOGEE Value Added Catalogue of Galactic globular cluster stars

Ricardo P. Schiavon, Siân G. Phillips, Natalie Myers +17

We introduce the SDSS/APOGEE Value Added Catalogue of Galactic Globular Cluster (GC) Stars. The catalogue is the result of a critical search of the APOGEE data release 17 (DR17) ca…
