Abstract

This thesis examines two suites of dark-matter-only simulations, at galaxy cluster and Milky Way scales, and compares their mass growth. Merger modes are found to be consistent, but with different inner structures. The thesis also presents a new technique for studying the neutral hydrogen gas content of distant galaxies, with the method applied to data from the DINGOVLA survey and a new measurement made of the cosmic gas density at z less than 0.1. The method is developed with future SKA-like interferometers in mind.
