Description
With an instrumented volume of 1km^3 of Antarctic ice, the IceCube Neutrino Observatory is the largest neutrino detector in the world. It is able to detect neutrinos with GeV to EeV energies and therefore covers a broad range of topics in particle and astroparticle physics. High-energy neutrinos from beyond our Earth and Galaxy would be ideal messenger particles to explore the yet unknown sources and acceleration mechanism of cosmic rays, because neutrinos propagate unaffected through the Universe. In searches for point-like steady and transient neutrino sources as well as diffuse neutrino fluxes, the completed IceCube detector reaches an unprecedented sensitivity. The large statistics of neutrinos and muons from cosmic ray air showers detected with the IceCube detector as well as with its surface component IceTop allows for cosmic ray anisotropy, spectrum and composition measurements around the knee. The study of neutrinos below 100 GeV with IceCube's low-energy extension DeepCore supplements classical neutrino oscillation experiments with its sensitivity to the deficit of atmospheric muon neutrinos at 25 GeV and searches for neutrinos from the annihilation of dark matter. This talk will summarize recent results.
