Measurement of the Diffuse Astrophysical Muon-Neutrino Spectrum with Ten Years of IceCube Data

Understand

The IceCube Neutrino Observatory measured a flux of high-energy astrophysical neutrinos in several detection channels.

• The energy spectrum is fitted as unbroken power-law, but different best-fit parameters were obtained in the various analyses covering different energy ranges between few TeV to 10 PeV.
• Here, we present an update to the analysis of through-going muon-neutrinos from the Northern Hemisphere.
• It was extended to almost ten years of data and an improved treatment of systematic uncertainties on the atmospheric fluxes was implemented.
