Residence times of CR protons (dashed) and electrons (dotted) in the CND of NGC 1068 as a function of the particle’s energy. Red lines n_H = 120 cm^-3, B_ISM = 100 μG, L_AGN = 2.1 × 10⁴⁵ erg s^-1, U_rad = 3.7 × 10⁴ eV cm^-3, R_shock = 100 pc, and v_shock = 200 km s^-1; black lines: n_H = 400 cm^-3, B_ISM = 350 μG, L_AGN = 4.2 × 10⁴⁴ erg s^-1, U_rad = 7.3 × 10³ eV cm^-3, R_shock = 100 pc, and v_shock = 200 km s^-1. The solid blue line indicates the timescale of the AGN-driven molecular outflow.
