AGN Beyond the 100pc Scale

Abstract

This chapter examines, using illustrative examples, the interactions between an AGN (supermassive black hole) and its host galaxy on spatial scales larger than those of the immediate nuclear surroundings defined by the size of the dusty torus. The influence of the ionizing and non-ionizing radiation and the effects of isotropic and jet-like outflows are discussed. The reasons for the two types of radiation anisotropy are explained and it is shown how this understanding has allowed a geometric unification of apparently diverse AGN types.
