Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational
dynamics, stellar evolution, and cosmology. Here, we review observations and theoretical …

The Gaia mission has revolutionized our view of the Milky Way and its satellite citizens. The
field of Galactic Archaeology has been piecing together the formation and evolution of the …

Context. The second Gaia data release (Gaia DR2) contains high-precision positions,
parallaxes, and proper motions for 1.3 billion sources as well as line-of-sight velocities for …

We analyse an N-body simulation of the interaction of the Milky Way (MW) with a Sagittarius-
like dSph (Sgr), looking for signatures which may be attributed to its orbital history in the …

We present the largest and most homogeneous catalog of H ii regions and associations
compiled so far. The catalog comprises more than 7000 ionized regions, extracted from 306 …

We describe the current plans for a spectroscopic survey of millions of stars in the Milky Way
galaxy using the Guo Shou **g Telescope (GSJT, formerly called the Large sky Area Multi …

In the first paper of this series, we present a new approach for studying the chemo-
dynamical evolution in disk galaxies, which consists of fusing disk chemical evolution …

We use the second data releases of the European Space Agency Gaia astrometric survey
and the high-resolution Galactic Archaeology with HERMES (GALAH) spectroscopic survey …

The spatial, kinematic, and elemental-abundance structure of the Milky Way's stellar disk is
complex, and has been difficult to dissect with local spectroscopic or global photometric …

The kinematics of the Milky Way disc as a function of age are well measured at the solar
radius, but have not been studied over a wider range of Galactocentric radii. Here, we …
