Evolution of active galactic nuclei jets are analyzed from their origin in accretion disks of active galactic nuclei to their destruction in far halos of galaxies. Based on analytical solutions of relativistic magnetohydrodynamics equations it is shown that interactions of charged jet with ambient intergalactic medium are not effective in jet destruction. High stability of jet in the nearest halo region is explained and confirmed. The model of active galactic nuclei jet deformation in far regions of galactic halos is presented. According to it, jets change their shapes due to scattering by black holes in halos. Numerical simulations of jet particle motion in the field of Schwarzschild black holes in a galactic halo are performed to support this model. Simulated shapes of jets are in good correspondence with observed data. It is shown that any known types of black holes (primordial, stellar, intermediate, and massive) could be responsible for jet deformation because of permissible values of their concentration in galactic halos. Other reasons of jet deformation are considered, and applicability of them is discussed.
Key words: galaxies, jets, halos, black hole physics
