Observational constraints on the influence of active galactic nuclei on the evolution of galaxies
This prize-winning Ph. D. thesis by Chris Harrison adopts a multi-faceted approach to address the lack of decisive observational evidence, utilising large observational data sets from several world-leading telescopes. Developing several novel observational techniques, Harrison demonstrated that ener...
