Cascaded photon spectra (colored lines) and all-flavor neutrino spectra (dashed black lines) for different values of the emission radius R for different parameter sets explored in this work. Among the photon spectra, solid lines correspond to ξ_B = 1, while dashed lines correspond to ξ_B = 0.01. All panels are made for injected cosmic-ray protons with s_CR = 2 and ﹩{\varepsilon }_{p}^{{\rm{\max }}}=30﹩ TeV. The solid black lines correspond to the 95% contour lines and the best-fit line from the IceCube data (R. Abbasi et al. 2022). Gamma-ray data from the Fermi-LAT (M. Ajello et al. 2023) and MAGIC (V. A. Acciari et al. 2019) observations are also shown.
