We develop a hybrid model of galactic chemical evolution that combines a multiring
computation of chemical enrichment with a prescription for stellar migration and the vertical …

Since the advent of Gaia astrometry, it is possible to identify massive accreted systems
within the Galaxy through their unique dynamical signatures. One such system, Gaia …

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 …

We investigate the inner regions of the Milky Way using data from APOGEE and Gaia EDR3.
Our inner Galactic sample has more than 26 500 stars within| X Gal|< 5 kpc,| Y Gal|< 3.5 …

Realistic models of the Galactic double white dwarf (DWD) population are crucial for testing
and quantitatively defining the science objectives of the Laser Interferometer Space Antenna …

The standard cosmological model predicts that galaxies are built through hierarchical
assembly on cosmological timescales,. The Milky Way, like other disk galaxies, underwent …

Over the last few years, many studies have found an empirical relationship between the
abundance of a star and its age. Here we estimate spectroscopic stellar ages for 178 825 …

Chemical abundances are an essential tool in untangling the Milky Way's enrichment
history. However, the evolution of the interstellar medium abundance gradient with cosmic …

Constraints on the formation and evolution of the Milky Way Galaxy require multidimensional
measurements of kinematics, abundances, and ages for a large population of stars. Ages for …

Bar formation and merger events can contribute to the rearrangement of stars within the
Galaxy in addition to triggering star formation (SF) epochs. Super-metal-rich (SMR) stars …
