Abstract

To constrain the contribution of source populations to the observed neutrino sky, we consider isotropic and anisotropic components of the diffuse neutrino data. We simulate through-going muon neutrino events by applying statistical distributions for the fluxes of extragalactic sources and investigate the sensitivities of current (IceCube) and future (IceCube-Gen2 and KM3NeT) experiments. The angular power spectrum is a powerful probe to assess the angular characteristics of neutrino data and we can already constrain rare and bright sources with current IceCube data. In addition, decaying and annihilating very heavy dark matter is a potential neutrino source, as suggested by the observed excess in the High-Energy Starting Event dataset. We apply an angular power spectrum analysis to HESE data for different dark matter models, allowing us to interpret the observed neutrino sky and perform a sensitivity forecast.
