Astronomical observations reveal a major deficiency in our understanding of physics—the
detectable mass is insufficient to explain the observed motions in a huge variety of systems …

The oldest, most metal-poor stars in the Galactic halo and satellite dwarf galaxies present an
opportunity to explore the chemical and physical conditions of the earliest star-forming …

We present the final sample of the Exploration of Local VolumE Satellites (ELVES) survey, a
survey of the dwarf satellites of a nearly volume-limited sample of Milky Way (MW)− like …

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 …

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 …

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 present new constraints on the star formation histories of six ultra-faint dwarf galaxies:
Bootes I, Canes Venatici II, Coma Berenices, Hercules, Leo IV, and Ursa Major I. Our …

Dwarf satellite galaxies are thought to be the remnants of the population of primordial
structures that coalesced to form giant galaxies like the Milky Way. It has previously been …

The lowest luminosity (L) Milky Way satellite galaxies represent the extreme lower limit of the
galaxy luminosity function. These ultra-faint dwarfs are the oldest, most dark matter …

Galactic archaeology based on star counts is instrumental to reconstruct the past mass
assembly of Local Group galaxies. The development of new observing techniques and data …
