Diffuse all-flavor neutrino flux spectrum. Burgundy markers show the IceCube diffuse flux spectrum as obtained from the most recent analysis of Basu et al. (2025). The solid black line shows the total flux. This comprises emission from AGN coronae predicted by our model (up to ∼10¹⁵ eV) and from jetted AGNs (BL Lac sources according to Padovani et al. 2015) at higher energies. The contribution of sources with different σ_p values is shown with dashed colored lines – see the legend.
