As part of the Gaia-ESO Survey (GES), a number of clusters will be observed that were chosen specifically for their massive-star content. We report on the...
Measurements of lithium in stars of different galactic populations such as young open clusters (Alpa Per, Pleiades, Praesepe, Coma, Hyades), very young stellar...
The Galactic underdogs: characterizing a population of metal-poor stars with disc kinematics in the Milky Way
To deepen our knowledge of the early history of the Milky Way, it is of particular interest to investigate the orbital and chemical properties of the most metal...
The GaLAxy Cluster Evolution survey (GLACE): introduction and first results
Aimed at understanding the evolution of galaxies in clusters, the GLACE survey is mapping a set of optical lines ([OII]3727, [OIII]5007, Hβ and Hα/[NII] when...
The GaLAxy Cluster Evolution Survey (GLACE): overview and status report
Aimed at understanding the evolution of galaxies in clusters, the GLACE survey is mapping a set of key optical lines in several galaxy clusters at z~0.40, 0.63...
The Galaxy-wide IMF - from Star Clusters to Galaxies
Over the past years observations of young and populous star clusters have shown that the stellar initial mass function (IMF) can be conveniently described by a...
RX J1211+2242 is an optically faint (B ≃ 19.2 mag) but X-ray bright (f2 - 10 keV = 5 × 10-12 erg cm-2 s-1) AGN, which has been shown to be a BL Lac object at...
