Description
The IceCube Neutrino Observatory is a cubic kilometer ice Cherenkov neutrino detector, located at the geographic South Pole, detecting neutrinos down to energies of about $10\,\textrm{GeV}$. Thanks to its size, IceCube can probe small fluxes of high-energy neutrinos $(\gt 10\,\textrm{TeV})$ and in the last couple of years it has established the existence of a high-energy astrophysical neutrino flux at the level of $0.5-2.5 \cdot 10^{-18} (E/100\,\textrm{TeV})^{-\gamma}\,\textrm{GeV cm}^{-2}\textrm{s}^{-1}\textrm{sr}^{-1}$ per flavor and a spectral index $\gamma$ of $2.0-2.7$ depending on the energy range of the specific analysis. DeepCore, a region of denser instrumentation at the lower center of the detector, detects low-energy atmospheric neutrinos $(\lt 100\,\textrm{GeV})$, which are used to study neutrino oscillations with a precision comparable to that of the leading experiments in the field. The latest results on both of these topics are discussed.
