TL;DR: In this article, the Gaia-ESO Public Spectroscopic Survey is using FLAMES at the VLT to obtain high-quality medium-resolution Giraffe spectra for about 10(5) stars and high-resolution UVES spectra of about 5000 stars.
Journal ArticleDOI
The variability of optically selected quasars
TL;DR: The variability properties of a sample of 300 optically selected quasars near the South Galactic Pole (SGP) have been studied over a baseline of 16 years using a series of twelve UK Schmidt Telescope B J plates at seven epochs.
Journal ArticleDOI
Precession of the Sagittarius stream

TL;DR: In this article, the path of the Sagittarius (Sgr) stream across the sky in Sloan Digital Sky Survey data is followed using a variety of stellar tracers, including blue horizontal branch stars, main-sequence turn-off stars and red giants.
Journal ArticleDOI
Big fish, small fish: Two New Ultra-Faint Satellites of the Milky Way
Vasily Belokurov,Matthew G. Walker,Nick Evans,Gerry Gilmore,Mike Irwin,D. Just,Sergey E. Koposov,Mario Mateo,Edward W. Olszewski,Laura L. Watkins,L. Wyrzykowski +10 more
TL;DR: In this article, the discovery of two new Milky Way satellites in the neighboring constellations of Pisces and Pegasus identified in data from the Sloan Digital Sky Survey is reported, and they use deep follow-up imaging obtained with the 4m Mayall telescope at Kitt Peak National Observatory to derive their structural parameters.
