Karazin Kharkiv National University popup.description2  ACTIVE GALAXY NUCLEI, GRAVITATIONALLY LENSED QUASARS, OBSCURING TORUS, CATALOGS We used photometric information from the ALLWISE and GaiaEDR3 catalogues, as well as spectroscopically confirmed extragalactic objects from the SDSS DR16 catalogue, to build a classification model and classify extragalactic objects such as AGN, quasars, and star-forming galaxies. The result of applying the classification model was a catalogue of extragalactic objects containing nearly 7 million objects. AGNs, quasars and star-forming galaxies were obtained using photometric information only. The average classification accuracy is 85% for AGN, 95% for quasars, and 92% for star-forming galaxies. In this paper we perform a numerical modelling of the AGNs, taking into account the dissipative forces and the influence of the wind in the torus throat, which significantly affect the accretion rate. The velocity maps of the torus clouds for different values of dissipation have been studied. The accretion velocity of the clouds for different values of dissipation and wind in the torus throat has also been studied. It is shown that taking into account the dissipation and the wind in the torus throat leads to a controlled accretion, which is carried out by feeding the accretion disk in portions, while maintaining the geometrically thick shape of the dust torus, which is required by a unified scheme of active galactic nuclei. Numerical simulations of the N-body problem of the dissipative torus and binary black hole system with additional external mass accretion to the torus are performed for the cases of joint rotation of the torus and binary black hole system and their counter-rotation. The experimental results show that the effect of clouds moving in opposite directions within the torus itself does not occur in these cases. It is concluded that the main mechanism of the detected counter-rotation in the torus of the Seyfert galaxy NGC 1068 is the influence of the asymmetric wind.
