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 …

Globular cluster (GC) systems have now been studied in galaxies ranging from dwarfs to
giants and spanning the full Hubble sequence of morphological types. Imaging and …

Abstract The Milky Way halo was predominantly formed by the merging of numerous
progenitor galaxies. However, our knowledge of this process is still incomplete, especially in …

Globular clusters (GCs) formed when the Milky Way experienced a phase of rapid assembly.
We use the wealth of information contained in the Galactic GC population to quantify the …

We use the age–metallicity distribution of 96 Galactic globular clusters (GCs) to infer the
formation and assembly history of the Milky Way (MW), culminating in the reconstruction of …

We search for excess γ-ray emission coincident with the positions of confirmed and
candidate Milky Way satellite galaxies using six years of data from the Fermi Large Area …

Positional, structural, and dynamical parameters for all dwarf galaxies in and around the
Local Group are presented, and various aspects of our observational understanding of this …

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 …

The outer disk of the Milky Way Galaxy is warped and flared. Several mechanisms have
been proposed to explain these phenomena, but none have quantitatively reproduced both …

If the favored hierarchical cosmological model is correct, then the Milky Way system should
have accreted~ 100-200 luminous satellite galaxies in the past~ 12 Gyr. We model this …
