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 …

The Milky Way's dwarf spheroidal satellites include the nearest, smallest and least luminous
galaxies known. They also exhibit the largest discrepancies between dynamical and …

Abstract The ACS Virgo Cluster Survey is a Hubble Space Telescope program to obtain high-
resolution imaging in widely separated bandpasses (F475W≈ g and F850LP≈ z) for 100 …

We report the first APOGEE metallicities and α-element abundances measured for 3600 red
giant stars spanning a large radial range of both the Large (LMC) and Small Magellanic …

Aims. As part of the DART project we have used the ESO/2.2 m Wide Field Imager in
conjunction with the VLT/FLAMES GIRAFFE spectrograph to study the detailed properties of …

For the first time we show the detailed, late-stage, chemical evolution history of a small
nearby dwarf spheroidal galaxy in the Local Group. We present the results of a high …

We present new radial velocity results for 176 stars in the Fornax dwarf spheroidal galaxy, of
which at least 156 are probable Fornax members. We combine with previously published …

We present new kinematic results for 387 stars near the Milky Way satellite dwarf spheroidal
galaxy Leo I. Spectra were obtained with the Hectochelle multiobject echelle spectrograph …

ABSTRACT The Advanced Camera for Surveys (ACS) Fornax Cluster Survey is a Hubble
Space Telescope program to image 43 early-type galaxies in the Fornax cluster, using the …

We present deep photometry in the B, V and I filters from CTIO/MOSAIC for about 270 000
stars in the Fornax dwarf spheroidal galaxy, out to a radius of r ell≈ 0.8 degrees. By …
