γ-ray and radio spectra for NGC 1068. AGN-driven outflow parameters are set at R_out = 100 pc, v_out = 200 km s^-1, and L_kin = 1.5 × 10⁴² erg s^-1; black lines: L_AGN = 4.2 × 10⁴⁴ erg s^-1, n_H = 10⁴ cm^-3, F_cal = 1, p = 2, η_p = 0.2, η_e = 0.02, B_ISM = 30μG (solid) and B_ISM = 2 mG (dashed); magenta line: L_AGN = 2.1 × 10⁴⁵ erg s^-1, n_H = 120 cm^-3, F_cal = 0.5, p = 2, η_p = 0.5, η_e = 0.4, B_ISM = 250μG; blue line: L_AGN = 4.2 × 10⁴⁴ erg s^-1, n_H = 10⁴ cm^-3, F_cal = 1, p = 2, η_p = 0.3, η_e = 0.1, B_ISM = 600μG. γ-ray spectrum: violet dotted line: expected CTA-south differential sensitivity, from simulated data (5σ per energy bin – five per decade – in 50 h, zenith angle = 20 deg ⁵), grey dotted line: measured MAGIC differential sensitivity (5σ in 50 h at low zenith angles <30 deg, Aleksić et al. 2016), orange dotted line: measured H.E.S.S. II differential sensitivity (5σ in 50 h, zenith angle =18 deg, Holler et al. 2015). Data points: Fermi-LAT spectrum from our analysis (red filled circles), and from the 3FGL catalogue (Acero et al. 2015, black open circles). Radio spectrum: primary electrons emission (dashed line), secondary electrons/positrons emission (dotted line), total emission (solid line). Data points: total radio emission from ≃200 pc region (circles, Sajina et al. 2011), extra-nuclear radio emission from ≃1.1 kpc region (triangle, Gallimore et al. 2006).
