Observations show that the central black hole in galaxies has a mass M of only ∼10−3 of the stellar bulge mass. Thus, whatever process grows the black hole also promotes star formation with far higher efficiency. We interpret this in terms of the generic tendency of active galactic nucleus (AGN) accretion discs to become self-gravitating outside some small radius Rsg∼ 0.01–0.1 pc from the black hole. We argue that mergers consist of sequences of such episodes, each limited by self-gravity to a mass ΔMepisode∼ 10−3M, with angular momentum characteristic of the small part of the accretion flow which formed it. In this picture, a major merger with ΔMmerger∼M gives rise to a long series of low-mass accretion disc episodes, all chaotically orien...
