Studies of interacting galaxies and the environmental effects on their evolution

Most galaxies in the Universe reside in groups, yet the physical processes that occur in group environments are not fully understood. This thesis studies galaxy interactions in group environments and the ramifications of these interactions on the evolution of the participant galaxies. I use the Australian Square Kilometre Array Pathfinder in combination with optical surveys to measure the baryon content of galaxies, the morphology and kinematics of their atomic gas, which contain information about their interactions with other galaxies. I also use the EAGLE simulations to interpret these observations and disentangle the role of group environments on galaxy evolution.
