The cosmic history of the baryon budget in a hierarchical universe
In the framework of the hierarchical model of galaxy formation, small primordial density fluctuations observed on the cosmological microwave background are amplified... -
Cosmological evolution of the physical properties of galaxies
The study of galaxy formation and evolution is one of today's hotest topics. Two large surveys (2dFGRS, SDSS), bearing on several million local galaxies, recently...
