The advent of the second data release of the Gaia mission, in combination with data from
large spectroscopic surveys, is revolutionizing our understanding of the Galaxy. Thanks to …

The evolution of the content of heavy elements in galaxies, the relative chemical
abundances, their spatial distribution, and how these scale with various galactic properties …

This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky
Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the …

The formation of our Milky Way can be split up qualitatively into different phases that resulted
in its structurally different stellar populations: the halo and the disk components,–. Revealing …

The Sloan Digital Sky Surveys (SDSS) have been almost continuously observing the skies
for over 20 yr, since the project began with a first phase in 1998 (SDSS-I; York et al. 2000) …

The ensemble of chemical element abundance measurements for stars, along with precision
distances and orbit properties, provides high-dimensional data to study the evolution of the …

To reach a deeper understanding of the origin of elements in the periodic table, we construct
Galactic chemical evolution (GCE) models for all stable elements from C (A= 12) to U (A …

Abstract Our Milky Way should host an ancient, metal-poor, and centrally concentrated
stellar population, which reflects the star formation and enrichment in the few most massive …

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 …
