Galaxy formation in the current cosmological paradigm is a very complex process where inflows, outlfows, interactions and mergers are common events. These processes can redistribute the angular momentum content of baryons. Recent observational results suggest that disc formed conserving angular momentum while elliptical galaxies, albeit losing angular momentum, determine a correlation between the specific angular momentum of the galaxy and the stellar mass. These observations provide stringent constrain for galaxy formation models in a hierarchical clustering scenario.We use cosmological hydrodynamical simulations that include an effective, physically-motivated Supernova feedback to analise the properties and formation history of a sample of galaxies of a cosmological simulation by performing a bulge-disc decomposition of the analysed systems and their progenitor systems.
