Abstract

This thesis explores how the dynamical interactions of dark matter haloes impact galaxy evolution and estimates how efficient different sources of stellar feedback are. We categorise haloes and subhaloes by their orbital history, using a dark matter-only N-body simulation. This allows us to invesitgate how these interactions imprint themselves on the distribution and internal structure of (sub)haloes. To study the evolution of galaxies impacted by different orbital histories, we employ the semi-analytic model Shark. Lastly, we estimate the impact of stellar feedback on the baryon content of galaxies using a Monte Carlo model for the evolution of a stellar population.
