Illustration showing the distribution of accretion and energy output of a model AGN. Gas infalling from the torus to the AGN is divided between accretion onto the SMBH Ṁ_acc and ejection Ṁ_jet. We assume the diffuse gas in the disk can be driven outwards by the AGN to give the overall ejection rate of gas Ṁ_wind,agn. The accretion onto the SMBH Ṁ_acc is itself divided in two parts: a fraction (1−f_ME)Ṁ_acc of the infalling gas goes to increasing the mass of the SMBH, while the remaining gas Q_agn = f_MEṀ_acc is converted into energy (see Sect. 5.3 for details). The radiative and mechanical energy of the AGN is then distributed in various ways as illustrated in Fig. 9.
