GALATEA: The 15-m Galactic Archaeology Spectroscopic Surveyor
Borja Anguiano, David Valls-Gabaud, Andrés del Pino +5
\textsc{GALATEA} (the \emph{Galactic Archaeology and Local-group Astrophysics Telescope for Extended Areas}) is a concept for a dedicated 15-m, wide-field, 10,000-fibre spectroscop…
Stellar Birth Radii in the LMC: Insights into Chemodynamics, Radial Migration, and Star Formation Across the Disk
Yuxi Lu, Bethany Garver, David L. Nidever +4
The LMC and SMC are interacting dwarf galaxies that offer a valuable testbed for studying the effects of galactic mergers. We investigate the chemodynamic history of the LMC in the…
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…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217
The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…
Counterculture Stars: Slow and Retrograde Stars with Low-Alpha Disk Abundances
Carrie Filion, Michael S. Petersen, Danny Horta +3
The Milky Way is home to a thin disk that can be defined via kinematics and/or elemental abundances. The elemental abundance-defined thin disk, also called the low-alpha disk, is g…
Hydrostatic and explosive -element chemical abundances of Milky Way globular clusters, halo substructures, and satellite galaxies
Danny Horta, Melissa K. Ness
Stellar atmospheric element abundance ratios of stars retain information about their birth conditions, helping elucidate their origin and nature. In this letter, we analyse and con…
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…
OTI on FIRE: Testing the Efficacy of Orbital Torus Imaging to Recover the Galactic Potential
Micah Oeur, Sarah R. Loebman, Adrian M. Price-Whelan +3
Orbital Torus Imaging (OTI) is a dynamical inference method for determining the Milky Way's gravitational potential using stellar survey data. OTI uses gradients in stellar astroph…
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…
: A generative, multi-output, latent-variable model for astronomical data with noisy labels
Danny Horta, Adrian M. Price-Whelan, David W. Hogg +2
The large volume of spectroscopic data available now and from near-future surveys will enable high-dimensional measurements of stellar parameters and properties. Current methods fo…
Vertical structure and kinematics of the LMC disc from SDSS/Gaia
Ó. Jiménez-Arranz, D. Horta, R. P. van der Marel +4
[Abbreviated] Context: Studies of the LMC's internal kinematics have provided a detailed view of its structure, largely by the exquisite proper motion data supplied by Gaia. Howeve…
