Formation of galaxies in Λcold dark matter cosmologies – I. The fine structure of disc galaxies

In this work we present a detailed analysis of the global and fine structure of four middle-mass disc galaxies obtained from hydrodynamic simulations in a Λcold dark matter (ΛCDM) scenario. These objects have photometric disc-to-total ratios in good agreement with those observed for late-type spirals, as well as kinematic properties in agreement with the observational I-band Tully–Fisher relation....
