Abstract: |
If there is a consensus that Active Nuclei are powered by accretion of gas onto a massive black hole, the structure and dynamics of the inflow remains poorly understood at the sub-parsec scale, not only in the hot, innermost region but also in the colder, outer ones. Our presentation will focus on these outer self-gravitating regions (beyond a few hundred Schwarzchild radii from the centre) where the disc mass, although relatively small, is expected to play a role, possibly dominant, on the disc evolution. Results derived from vertically averaged and vertically stratified disc models will be discussed. Some important consequences for the problem of AGN fueling will be mentioned. |
