Seminar Thorsten Glüsenkamp: Analysis of the cumulative neutrino flux from Fermi-2LAC blazars with 3 years of IceCube data
The recent discovery of a diffuse neutrino flux up to PeV energies raises the question of which populations of astrophysical sources contribute to this diffuse signal. One extragalactic candidate source population to produce high-energy neutrinos are blazars. This talk gives a brief overview over the current status of the TeV-PeV neutrino flux and then discusses an analysis that has searched for the cumulative flux contribution from a large population (~ 900 sources) of GeV emitting blazars. The talk ends with the results of the analysis and its implications for the astrophysical TeV-Pev neutrino flux as well as for prevailing theoretical predictions for the neutrino flux from blazars.
