Scientific paper

Models to explain the formation and collimation of beams of gas in active galactic nuclei are discussed. A model with a black hole as prime mover is outlined. The fact that the overall luminosity of radiation supported tori can be largely super-Eddington and that it is emitted mostly within the two narrow funnels which characterize these configurations, provides a plausible way to accelerate matter up to relativistic velocities. The funnels are filled with fully ionized plasma, continuously lost from the disk surface through a mechanism analogous to the stellar wind. As a consequence of the competing action of the gravitational and radiative forces a stagnation point exists in the funnel. Depending on the strength of the radiative forces, gas is accelerated outwards, or, where gravity prevails, the flow is directed inwards and ultimately swallowed by the hole.
