Abstract

This thesis uses state-of-the-art hydrodynamical simulations and novel analysis techniques to shed light on the gas flows that surround galaxies. We demonstrate that the rate and nature of halo-scale gas accretion is strongly influenced by galaxy-scale feedback (from both stars and active galactic nuclei); and also detangle the different mechanisms behind the observed depletion of gas in satellite galaxies. Our work suggests that the properties of the circum-galactic medium are particularly sensitive to how feedback is implemented, making it the ideal test-bed for assessing the accuracy of feedback models used in cosmological simulations.
