Multi-messenger SED of NGC 4151 in the VHE band. Black points indicate the MAGIC ULs derived in this work assuming a power-law spectral index Γ = 2.83. The orange solid line and band refer to the best-fit and 1σ contour of the single-flavor neutrino spectrum derived from IceCube data collected from muon tracks over 12 years (Abbasi et al. 2025b), while the dotted orange line corresponds to its extrapolation in energy. The green band refers to the single-flavor neutrino spectrum derived from the publicly available 10-year IceCube dataset (adapted from Neronov et al. 2024).
