Cumulative γ-ray (left) and neutrino (right) background from AGN winds predicted by our SAM. Model predictions are shown for our fiducial model and for different AGN wind spectral energy parameters: p = 2.2 (purple lines), p = 2.3 (blue lines), B = B_ISM (solid lines), and B = B_shock dashed lines. The circles represent Fermi-LAT data (Ackermann et al. 2015). The squares show the differential model of IceCube neutrino data, while purple dotted lines represent the power-law models (Aartsen et al. 2015).
