Abstract: AGN feedback is now widely believed to play a crucial role in the co-evolution between the central black hole and its host galaxy.Two feedback modes have been identified, namely the radiative and kinetic modes,which correspond to the luminous AGNs and lowluminosityAGNs (LLAGNs), respectively. In this talk, I will briefly review these feedback processes, and focus on the radiative heating in the kinetic mode. Radiative heating in the kinetic mode is potentially important because (1) the radiation power of LLAGNs is higher than the jet power over a wide parameter range, (2) the spectral energy distribution of LLAGNs is such that the radiative heating is more effective compared to that of luminous AGNs with the same luminosity, and (3) most of the time in the lifecycle of an AGN is spent in the LLAGNs phase. With up-to-date characteristic broadband spectral energy distributions of LLAGNs, we calculate the value of “Compton temperature” (T_C), which determines the radiative heating by Compton scattering. We also compare this heatingprocess with other radiative heating and cooling processes such as photoionization/recombination. Our result can be used for an accurate calculation of the radiative heating in the study of AGN feedback, where we highlight several applications in our group.
