RADIO PHYSICS AND RADIO ASTRONOMY

In the framework of N-body simulations, we have investigated the influence of initial conditions on the evolution of self-gravitating torus being in the active galactic nuclei (AGN), as well as evolution of distribution of particles (clouds) by their orbital elements analysed. The results of simulations show that stability of a geometrically thick torus in AGN can be explained by the motion of clouds in the torus by inclined and eccentric orbits. The scenario of torus formation being related to the beginning of the AGN’s stage is suggested.
