| This dissertation presents various physics and astronomy results with upward going muons using the first five years of data from the Super-Kamiokande detector, which is a 50 kiloton water Cherenkov detector located in Japan. Upward muons produced by neutrinos interacting in the rock below the detector represent the highest energy neutrinos seen in Super-Kamiokande.; Using these events, I have searched for the signatures of annihilations of dark matter particles to high energy neutrinos in the center of Earth, Sun and the Galactic Center. Constraints on dark matter scattering cross-sections with nuclei using these results will be presented. Space-time coincidences from astrophysical transient sources such as gamma-ray bursts and soft gamma-ray repeaters are reported.; I have developed an algorithm to isolate a sample of events, called “showering upward going muons”, which lose energy through radiative processes. We shall use this subset, whose parent neutrino energy is approximately 1 TeV, to do astrophysical searches in the high energy region, where the atmospheric neutrino background is reduced. |
