Description
IceCube is a cubic-kilometer neutrino observatory buried deep in the ice sheet
at the geographic South Pole. The data from its first few years of operation
have revealed an excess of high-energy neutrino events in multiple detection
channels that is incompatible with purely atmospheric origins, which we
interpret as evidence for a flux of neutrinos from unresolved astrophysical
sources. At the same time, no point sources of neutrinos have been detected.
This talk will provide an overview of IceCube's constraints on the energy
spectrum and neutrino flavor composition of the diffuse astrophysical neutrino
flux.
