Abstract: Mergers and interactions of galaxies are of fundamental importance for galaxy formation and evolution in modern hierarchical cosmologies. We demonstrate how new, high-resolution numerical simulations of nearby interacting galaxies, like the spectacular Antennae galaxies, finally help understanding important physical processes during galaxy mergers. Towards higher redshift major and, more importantly, minor mergers, might play the dominant role for the strong size evolution of massive early-type galaxies. On this topic we present recent results from high-resolution simulations in a full cosmological context which offer an alternative to the traditional disk-merger paradigm.
