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 …

Using a large sample of main sequence stars with 7D measurements supplied by Gaia and
SDSS, we study the kinematic properties of the local (within∼ 10 kpc from the Sun) stellar …

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 …

We report the discovery of eight new ultra-faint dwarf galaxy candidates in the second year
of optical imaging data from the Dark Energy Survey (DES). Six of these candidates are …

We study the link between baryons and dark matter (DM) in 240 galaxies with spatially
resolved kinematic data. Our sample spans 9 dex in stellar mass and includes all …

We report the discovery of eight new Milky Way companions in $\sim 1800\;{\mathrm
{deg}}^{2} $ of optical imaging data collected during the first year of the Dark Energy Survey …

A proper understanding of the Milky Way (MW) dwarf galaxies in a cosmological context
requires knowledge of their 3D velocities and orbits. However, proper motion (PM) …

We report the results of a systematic search for ultra-faint Milky Way satellite galaxies using
data from the Dark Energy Survey (DES) and Pan-STARRS1 (PS1). Together, DES and PS1 …

Abstract The Apache Point Observatory Galactic Evolution Experiment (APOGEE), one of the
programs in the Sloan Digital Sky Survey III (SDSS-III), has now completed its systematic …
