Resum

I will present a new semi-analytical model of galaxy formation, GECO (Galaxy Evolution COde), aimed at a better understanding of when and how the two processes of star formation and galaxy assembly have taken place, by comparison with a wide variety of recent data. I will introduce the basis of the semi-analytical approach and the baryonic physics - gas cooling, star formation, feedback - included in the model. Then, I will show the ability of the model in reproducing both local boundary conditions, such as the local stellar mass function, and high-redshift data, focusing in particular on the time-scales of stellar formation and mass assembly, as constrained by near and far-IR surveys.
