Shown is an artist's representation of cosmic neutrinos that are detected by IceCube. The event type shown is a cascade event, which was used in both analyses. The inset figure shows the combined fit to the diffuse extragalactic astrophysical neutrino flux normalization. Credit: Brad Sherman, IceCube Collaboration
