Latest results and future perspectives of IceCube and IceCube-Gen2 — •Jan Auffenberg for the IceCube collaboration — Physikalisches Institut III B, RWTH Aachen University
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 GeV. Thanks to its size, IceCube can probe small fluxes of high-energy neutrinos (> 10 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 · 10−18 (E/100 TeV)−γ GeV−1 cm−2s−1sr−1 per flavor and a spectral index γ of 2.0−2.7 depending on the energy range and the underlying physics assumptions of the specific analysis. Features in the spectral shape, the flavor composition, and the identification of sources of this astrophysical neutrinos are central points of current analysis and are benchmark for future plans with IceCube-Gen2. DeepCore, a region of denser instrumentation at the lower center of the detector, detects low-energy atmospheric neutrinos (< 100 GeV), which are used to study neutrino oscillations with a precision comparable to that of the leading experiments in the field. The latest results and future plans of IceCube are discussed.
