The SAURON survey has revised our view of early type galaxies discovering that central disks and multiple kinematic components are common; 75% of the sample...
Transitions from Clumpy to Smooth Galaxies over Cosmic Time
Galaxies at redshifts z~2-5 are dominated by clumpy morphologies instead of the more familiar elliptical and spiral types seen in the local Universe. The clumpy...
Large-scale outflows from galaxies are a crucially important yet poorly understood aspect of galaxy evolution. They redistribute gas and metals into the IGM...
Unveiling 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...
Using 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...
What 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...
What 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...
XMM-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...
