Original · EN

From a set of 3D cosmological simulations which incorporate a self-consistent model of the star-gas interactions, we have been able to obtain a statistically significant sample of galaxy-type halos with observational properties, like colors and luminosities. Using this data-base, we have studied general relations of galaxies, such as the Tully-Fisher relation, luminosity functions, environmental dependences, or cosmic star formation density.
