TL;DR: In this paper, the authors present abundances of Fe, Na, and O for 1409 red giant stars in 15 galactic globular clusters (GCs), derived from the homogeneous analysis of high-resolution FLAMES/GIRAFFE spectra.

TL;DR: The Gaia-ESO Public Spectroscopic Survey has begun and will obtain high quality spectroscopy of some 100000 Milky Way stars, in the field and in open clusters, down to magnitude 19, systematically.

TL;DR: In this paper, a new determination of the metallicity distribution, age, and luminosity function of the Galactic bulge stellar population is presented, which is the most extended and complete LF so far obtained for the galactic bulge, by combining near-IR data from the SOFI imager at ESO NTT and the NICMOS camera on board HST.

TL;DR: A new UV-initiative Hubble Space Telescope project (GO-13297) is described in this paper that will complement the existing F606W and F814W database of the Advanced Camera for Surveys Globular Cluster (GC) Treasury by imaging most of its clusters through UV/blue WFC3/UVIS filters F275W, F336W, and F438W.
