For CRs injected with a power-law energy spectrum $\propto E^{-2}$, we find that clusters contribute to the diffuse flux observed by the IceCube Neutrino Observatory with up to $\sim 20 \;\%$.

Our results suggest that plasma instabilities can describe the spectra of some blazars and mimic the effects of IGMFs, depending on parameters such as intrinsic spectrum of the object, the density and temperature of the IGM, and the luminosity of the beam.
