Abstract

The interplay between galaxies and their dark matter haloes is not fully understood. For example, drivers of asymmetry in cold, gaseous disks, and the relationship between their H2 content, environment, and redshift are not well established, nor is the connection between galaxy properties and the dynamical state of their host haloes. This thesis addresses these questions using state-of-the-art cosmological simulations. We specifically address the physical origin of disk asymmetries (Chapter 3),study how the dynamical state of haloes affects their galaxy populations (Chapter 4), and determine the role of environment in establishing the molecular mass of a galaxy (Chapter 5).
