Description
Matter around black holes is usually modeled neglecting its self-gravity, i.e., assuming a fixed background metric. In these lectures I will focus on the opposite case, in which the self-gravity of matter is taken into account. Simple general-relativistic systems in which the effects of self-gravity can be studied include axially symmetric configurations - stationary disks (or tori) around black holes - or spherically symmetric steady accretion flows. I will consider mostly hydrodynamical or magentohydrodynamical models. The interplay between the structure of spacetime affected by the self-gravity of matter and the motion of matter around black holes leads to several interesting phenomena, which I will shortly discuss: bifurcations of solutions, occurrence of various ergoregions, changes in the phase-space of geodesic orbits.
