The evolution of disk galaxies

We study the evolution of disk galaxies using galaxy evolutionary models with initial and boundary conditions linked to the hierarchical formation scenario. Disks galaxies are modeled locally within growing cold dark matter halos and including a physical model for star formation. We focus our attention on predictions of the star formation history, size and surface brightness evolution and the evolution of the H- and B-band Tully-Fisher relations. Comparisons with available observational data are presented.
