After the Big Bang, production of heavy elements in the early Universe takes place starting
from the formation of the first stars, their evolution, and explosion. The first supernova …

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 …

Context. The Gaia-ESO Public Spectroscopic Survey is an ambitious project designed to
obtain astrophysical parameters and elemental abundances for 100 000 stars, including …

We present results from the" Mint" resolution DC Justice League suite of Milky Way–like
zoom-in cosmological simulations, which extend our study of nearby galaxies down into the …

We combine Gaia early data release 3 astrometry with accurate photometry and utilize a
probabilistic mixture model to measure the systemic proper motion of 52 dwarf spheroidal …

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 …

Aims. We perform a comprehensive determination of the systemic proper motions of 74
dwarf galaxies and dwarf galaxy candidates in the Local Group based on Gaia early data …

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 …

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 …

We report the kinematic, orbital, and chemical properties of 12 stellar streams with no
evident progenitors using line-of-sight velocities and metallicities from the Southern Stellar …
