Modeling the Extragalactic Gamma Ray Background Spectrum with Very High Energy Gamma Ray Data — •Felix Neubürger for the IceCube collaboration — Technische Universität Dortmund

With the origin of the astropysical neutrinos observed by IceCube not being completely resolved, a closer look at possible sources is needed.

A recent analysis by the IceCube Collaboration suggests that blazars detected by Fermi are responsible for less than a third of the observed neutrino flux.

Research by Broderick et al. considers plasma beam instabilities in a more generalised model for the EGRB leading to a more fitting blazar distribution in the unified AGN-Paradigm.

For Very High Energy Gamma-Rays this distribution leads to a diffuse flux matching the Fermi data.

The goal of the presented work is to calculate the diffuse neutrino flux supposedly generated by unresolved blazars based on the assumptions made by Broderick et al. for the Extragalactic Gamma-Ray Background using new data. This will then be compared to the diffuse flux measured by IceCube.

This talk presents an outline of the methodology used to calculate the neutrino flux from the suggested Blazar distribution.
