Recent results on astrophysical neutrinos from IceCube

A diffuse flux of astrophysical neutrinos above 100 TeV has been observed at the IceCube Neutrino Observatory at the South Pole, opening the new field of neutrino astronomy. New observations have now the measured the energy spectrum of the astrophysical flux down to 10 TeV and found it broadly consistent with a power-law. Constraints on the flavor composition of the astrophysical flux have also been derived, which can discern various neutrino production models and probe non-standard physics like neutrino decay and Lorentz violation. Lastly, limits on point and time-dependent sources of astrophysical neutrinos will be presented, along with the implications of these results for the origin of the diffuse flux.
