Context. We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources brighterExpand
Beasts of the Southern Wild: Discovery of nine Ultra Faint satellites in the vicinity of the Magellanic Clouds
We have used the publicly released Dark Energy Survey data to hunt for new satellites of the Milky Way in the Southern hemisphere. Our search yielded a large number of promising candidates. In thisExpand
Dry Mergers in GEMS: The Dynamical Evolution of Massive Early-Type Galaxies
We have used the 28' × 28' Hubble Space Telescope image mosaic from the GEMS (Galaxy Evolution from Morphology and SEDs) survey in conjunction with the COMBO-17 photometric redshift survey toExpand
Co-formation of the disc and the stellar halo
Using a large sample of Main Sequence stars with 7-D measurements supplied by Gaia and SDSS, we study the kinematic properties of the local (within ∼10 kpc from the Sun) stellar halo. WeExpand
Cats and dogs, hair and a hero: A quintet of new milky way companions
We present five new satellites of the Milky Way discovered in Sloan Digital Sky Survey (SDSS) imaging data, four of which were followed-up with either the Subaru or the Isaac Newton Telescopes. TheyExpand
The Catalina Surveys Periodic Variable Star Catalog
We present ~47,000 periodic variables found during the analysis of 5.4 million variable star candidates within a 20,000 deg^2 region covered by the Catalina Surveys Data Release-1 (CSDR1). CombiningExpand
The Luminosity Function of the Milky Way Satellites
We quantify the detectability of stellar Milky Way satellites in the Sloan Digital Sky Survey (SDSS) Data Release 5. We show that the effective search volumes for the recently discoveredExpand
Constraining the Milky Way Potential with a Six-Dimensional Phase-Space Map of the GD-1 Stellar Stream
The narrow GD-1 stream of stars, spanning 60? on the sky at a distance of ~10?kpc from the Sun and ~15?kpc from the Galactic center, is presumed to be debris from a tidally disrupted star clusterExpand
The DESI Experiment Part I: Science,Targeting, and Survey Design
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through redshift-spaceExpand
Kinematics and chemistry of recently discovered Reticulum 2 and Horologium 1 dwarf galaxies
We report on VLT/GIRAFFE spectra of stars in two recently discovered ultra-faint satellites, Reticulum 2 and Horologium 1, obtained as part of the Gaia-ESO Survey. We identify 18 members in ReticulumExpand
