Unscaled sketch of the AGN unification theory. A type 1 AGN is seen at inclinations 0°–60°, while a type 2 AGN is seen at approximately 60°–90°. Colour-coding: the central super massive black hole is in black, the surrounding X-ray corona is in violet, the multi-temperature accretion disc is shown with the colour pattern of a rainbow, the broad-line region is in red and light brown, the circumnuclear dust is in dark brown, the polar ionized winds are in dark green, and the final extension of the narrow line region is in light green. A double-sided, kilo-parsec jet is added to account for radio-loud AGN. From Marin et al. (2016a).
