Robust data-driven metallicities for 175 million stars from Gaia XP spectra
We derive and publish data-driven estimates of stellar metallicity [M/H] for∼ 175 million stars
with low-resolution XP spectra published in Gaia DR3. The [M/H] values, along with T eff and …

StarHorse results for spectroscopic surveys and Gaia DR3: Chrono-chemical populations in the solar vicinity, the genuine thick disk, and young alpha-rich stars
The Gaia mission has provided an invaluable wealth of astrometric data for more than a
billion stars in our Galaxy. The synergy between Gaia astrometry, photometry, and …

Nitrogen enrichment and clustered star formation at the dawn of the Galaxy
Anomalously high nitrogen-to-oxygen abundance ratios [N/O] are observed in globular
clusters (GCs), among the field stars of the Milky Way (MW), and even in the gas in az≈ 11 …

Stellar halo substructure generated by bar resonances
Using data from the Gaia satellite's Radial Velocity Spectrometer Data Release 3 (RVS,
DR3), we find a new and robust feature in the phase-space distribution of halo stars. It is a …

In-situ versus accreted Milky Way globular clusters: a new classification method and implications for cluster formation
We present a new scheme for the classification of the in-situ and accreted globular clusters
(GCs). The scheme uses total energy E and z-component of the orbital angular momentum …

Taking the Milky Way for a spin: disc formation in the artemis simulations
We investigate the formation (spin-up) of galactic discs in the artemis simulations of Milky
Way (MW)-mass galaxies. In almost all galaxies, discs spin up at higher [Fe/H] than the MW …

The three-phase evolution of the Milky Way
We illustrate the formation and evolution of the Milky Way over cosmic time, utilizing a
sample of 10 million red giant stars with full chemodynamical information, including …
