DESCRIPTION:Understanding the physical processes driving the formation and
  evolution of galaxies across the cosmic epochs is one of the most importa
 nt goals of modern Astrophysics.\nObservations obtained through major astr
 onomical facilities\, together with theoretical modelling and cosmological
  numerical simulations\, have enabled impressive progress in this field.\n
 I will present some of the main results obtained in the recent years. In p
 articular\, I will shortly review what we know about the infancy of galaxi
 es and the processes responsible for the formation and assembly of stars a
 t different cosmic times.\nInterestingly\, across the entire life of the U
 niverse\, these processes managed to convert into stars only 4% of the ava
 ilable baryons\, revealing that star formation has been globally very inef
 ficient.\nSome mechanism must be responsible for regulating star formation
  in galaxies and preventing them from overgrowing. Some of these mechanism
 s must be effective enough to completely quench star formation in a signif
 icant fraction of galaxies\, effectively leading to their "death" (resulti
 ng into the large population of local passive and quiescent galaxies).\nVe
 ry interesting is also the finding that additional processes can also "rej
 uvenate" some of these galaxies and activate new and unexpected channels o
 f star formation. Major progress has been achieved in identifying the key 
 mechanisms responsible for these fascinating phenomena\, however several r
 ecent puzzling observational findings have yet to be fully understood.\nMa
 jor new astronomical observing facilities are currently being developed\; 
 they will certainly enable us to tackle many of the outstanding open quest
 ions and are expected to shed new light on the physical mechanisms regulat
 ing the formation and evolution of galaxies.\nCambridge is heavily involve
 d in these new facilities and I will shortly discuss the plans for their e
 xploitation.\n
