TalkA multiwavelength look into the common evolution of luminous quasars and their host-galaxies
This talk will be dedicated to luminous (LBol~1E47 erg/s), high-redshift quasars, which are ideal targets to investigate (i) feedback from SMBHs, and (ii) the...

TalkA new framework for investigating the evolution of Early Type Galaxies
I present a detailed analysis of the scaling relations of ETGs and suggest a way to predict the evolution of the distributions of galaxies in these planes. This...

NewsA study shows the unexpected effect of black holes beyond their own galaxies
At the heart of almost every sufficiently massive galaxy there is a black hole whose gravitational field, although very intense, affects only a small region...
