Contribution to the diffuse neutrino flux (orange shaded region) of J1406-like radio-loud DOGs (red star) and IceCube detectability (black and gray shaded regions). This figure is made following Figure 3 of K. Murase & E. Waxman (2016). When the radio-loud DOGs have a small reduction factor (e.g., f_bol = 10; red star), they can locate above the required ﹩{L}_{{\nu }_{\mu }}^{{\rm{eff}}}﹩ and n₀ for a redshift evolution of α ∼ 8 (the bottom part of the orange shaded region).
