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…
A Comparative Analysis of the Chemical Compositions of Gaia-Enceladus/Sausage and Milky Way Satellites using APOGEE
Laura Fernandes, Andrew C. Mason, Danny Horta +11
We use data from the 17th data release of the Apache Point Observatory Galactic Evolution Experiment (APOGEE 2) to contrast the chemical composition of the recently discovered Gaia…
Is Terzan 5 the remnant of a building block of the Galactic bulge? Evidence from APOGEE
Dominic J. Taylor, Andrew C. Mason, Ricardo P. Schiavon +16
It has been proposed that the globular cluster-like system Terzan 5 is the surviving remnant of a primordial building block of the Milky Way bulge, mainly due to the age/metallicit…
APOGEE Detection of N-rich stars in the tidal tails of Palomar 5
Sian G. Phillips, Ricardo P. Schiavon, J. Ted Mackereth +15
Recent results from chemical tagging studies using APOGEE data suggest a strong link between the chemical abundance patterns of stars found within globular clusters, and chemically…
An enquiry on the origins of N-rich stars in the inner Galaxy basedon APOGEE chemical compositions
Shobhit Kisku, Ricardo P. Schiavon, Danny Horta +10
Recent evidence based on APOGEE data for stars within a few kpc of the Galactic centre suggests that dissolved globular clusters (GCs) contribute significantly to the stellar mass…
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…
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…
