We analyze long-term evolution of jets from their origin in accretion disks of active galactic nuclei to their destruction in far-halos of galaxies. Based on the analytical solutions of relativistic magnetohydrodynamics equations we show that interactions of charged jet with intergalactic medium are not effective in jet destruction. High stability of jet in the nearest halo region are explained and proved. We show that the only mechanism of jet particles changing their trajectories is their interaction with cold dark matter particles in far regions of galactic halo. Numerical simulations result in the most probable candidate for such cold dark matter particles --- primordial micro black holes.
Key words: galaxies: active, galaxies: jets, black hole physics
