Abstract The SDSS-IV Apache Point Observatory Galactic Evolution Experiment (APOGEE)
survey has obtained high-resolution spectra for thousands of red giant stars distributed …

We report the first APOGEE metallicities and α-element abundances measured for 3600 red
giant stars spanning a large radial range of both the Large (LMC) and Small Magellanic …

Aims. We explore correlations between the strength of metallicity gradients in Local Group
dwarf galaxies and their stellar mass, star formation history timescales, and environment …

We present a Bayesian method to identify multiple (chemodynamic) stellar populations in
dwarf spheroidal galaxies (dSphs) using velocity, metallicity, and positional stellar data …

We present GaiaHub, a publicly available tool that combines Gaia measurements with
Hubble Space Telescope (HST) archival images to derive proper motions (PMs). It increases …

We use a sample of 73 simulated satellite and central dwarf galaxies spanning a stellar
mass range of 10 5.3–10 9.1 M⊙ to investigate the origin of their stellar age gradients. We …

We present a detailed study of the internal structure and kinematics of the core of the
Sagittarius dwarf spheroidal galaxy (Sgr). Using machine-learning techniques, we have …

We have studied the extent of the Red Giant Branch stellar population in the Fornax dwarf
spheroidal galaxy using the spatially extended and homogeneous data set from Gaia EDR3 …

We present an analysis of the kinematics of 14 satellites of the Milky Way (MW). We use
proper motions (PMs) from the Gaia Early Data Release 3 (EDR3) and line-of-sight …

We present a new derivation of the star formation history (SFH) of the dSph galaxy Fornax in
two central regions, characterized by unprecedented precision and age resolution. It reveals …
