Title:
Hierarchical Galaxy Formation
***********************************************************
Abstract:
I will present a new code for the formation of galaxies in the context
of the hierarchical LambdaCDM model. After discussing the hierarchical
galaxy formation paradigm, I will outline the merits and problems of the
codes based on semi-analityc techniques. Our new model improves
in the level of sophistication at which the various physical processes are
treated. In comparison with other similar codes, it reproduces correctly the
assembly of stellar mass in the Universe without making ad-hoc assumptions
on the behaviour of starbursts at high redshift. However, the presence of
old
compact galaxies at z=0 and the lack of proper quenching of cooling flows
at low redshift reveals that some physical ingredient are still missing.
