Neutrino Fluxes (image) Johannes Gutenberg Universitaet Mainz Share Print E-Mail Caption This figure shows various neutrino fluxes as a function of neutrino energy. The neutrino energy is expressed in GeV (1 GeV = 1 billion eV). IceCube data points and upper limits of astrophysical neutrino fluxes from other experiments are also shown here.
