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 …

The emergence of the first sources of light at redshifts of z∼ 10–30 signaled the transition
from the simple initial state of the Universe to one of increasing complexity. Recent progress …

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

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 spectroscopic metallicities of individual stars in seven gas-rich dwarf irregular
galaxies (dIrrs), and we show that dIrrs obey the same mass–metallicity relation as the dwarf …

Abstract The Subaru Prime Focus Spectrograph (PFS) is a massively multiplexed fiber-fed
optical and near-infrared three-arm spectrograph (N fiber= 2400, 380≤ λ≤ 1260 nm, 1 3 …

We introduce a method for measuring the slopes of mass profiles within dwarf spheroidal
(dSph) galaxies directly from stellar spectroscopic data and without adopting a dark matter …

We present the stellar atmospheric parameters (effective temperature, surface gravity,
overall metallicity), radial velocities, individual abundances, and distances determined for …

We present metallicity distribution functions (MDFs) for the central regions of eight dwarf
satellite galaxies of the Milky Way: Fornax, Leo I and II, Sculptor, Sextans, Draco, Canes …

We present the results of a comprehensive Keck/DEIMOS spectroscopic survey of the ultra-
faint Milky Way satellite galaxy Segue 1. We have obtained velocity measurements for …
