CharlaUnbiased studies of galactic outflows
Large-scale outflows from galaxies are a crucially important yet poorly understood aspect of galaxy evolution. They redistribute gas and metals into the IGM...

CharlaUnveiling the inner Milky Way globular cluster system
A serious limitation in the study of the Galactic inner halo and bulge globular clusters has been the existence of large and differential extinction by...

CharlaUsing nitrogen as a tracer of the chemical content of the Universe: from WR nebulae to early star-forming galaxies
Chemical abundances derived using emission-line spectra in ionized gaseous nebulae are between the most useful properties that can be derived to understand the...

CharlaWhat is the Milky Way outer halo made of? High resolution spectroscopy of distant red giants
In a framework where galaxies form hierarchically, extended stellar haloes are predicted to be an ubiquitous feature around Milky Way-like galaxies and to...

CharlaWhat is the role of the environment in shaping early-type galaxy sizes? Did it changed in the last 10 Gyr?
Understanding galaxy evolution requires understanding the impact of cosmic time, environment, mass, and halo growth at least, because likely a combination of...

CharlaXMM-Newton and Chandra combined analysis of the most massive galaxy clusters at z~1
We present a detailed study of the spatially resolved thermodynamic and hydrostatic mass profiles of the five most massive clusters detected at z~1 via the...
