Pinpointing the Origins of Fast Radios Bursts

One of the great mysteries of modern astrophysics, fast radio bursts (FRBs) are short-duration, energetic bursts of radio-wavelength emission predominantly originating outside the Galaxy. This thesis enriches our current understanding of FRBs, investigating the temporal and spectral properties of the largest (to date) sample of localised FRBs, shedding light on the environments through which they traverse and furthering our understanding of the universe. It also presents the development of receiver technology engineered to facilitate localisation of FRBs --thereby associating individual signals to their host galaxies --and investigates the accuracy of positions attainable with the Australian Square Kilometre Array Pathfinder.
