Cosmic ray (markers), neutrino (dashed lines) and photon (solid lines) spectra (E² × dN/dE) for the dip model compared to Auger spectrum (Abraham et al. 2010a,b; open circles) and the Fermi diffuse gamma-ray spectrum (Abdo et al. 2010; black squares). The contribution of the pion mechanism to the photon spectrum is shown (dashed lines). The chosen spectral indices are β = 2.6 for the uniform case (no evolution), 2.5 for SFR and 2.3 for FR-II. The results were computed assuming the IR/Opt/UV background estimate from Stecker et al. 2006 (top) and Kneiske et al. 2004 (bottom). In the top panel the Auger 90% C.L integrated upper limit (2 years) for tau neutrinos assuming a pure E^-2 neutrino spectrum is also shown for comparison (Abraham et al. 2011; the line represents the central value and was multiplied by 3 assuming a complete mixing of the neutrino flavors). The equivalent IceCube limit (IC-40, red thick-dashed line) is also shown (Abbasi et al. 2011).
