Number of UFOs with a gamma-ray signal above the typical sensitivity of the CTAO (50 hours) and below the Fermi-LAT sensitivity. The shock radius is Rsh = 1 pc. Panels from top to bottom illustrate different assumptions of external density: n0 = 102 − 103 − 104 cm−3. Sensitivities of Fermi-LAT (14 years), LHAASO (5 years) and KM3NeT/ARCA (10 years) are shown.
