In a framework where galaxies form hierarchically, extended stellar haloes are predicted to be an ubiquitous feature around Milky Way-like galaxies and to...

Understanding galaxy evolution requires understanding the impact of cosmic time, environment, mass, and halo growth at least, because likely a combination of...

Recent advances in 3D model atmospheres have led to a significant downward revision in photospheric heavy element abundance estimates for the Sun, especially...
