Interaction of Active Galactic Jets with Dark Matter Substructures

Abstract

In this paper we study the interaction of jets with galactic haloes via scattering by cold dark matter subhaloes and gravitational lensing. We show that lensing of jet radiation by halo masses is negligible and could not be observed. We consider the effect of broadening of jets due to scattering of its particles by gravitational field of dark matter subhaloes. We apply analytical estimation and construct precise numerical model to determine the effects of dark matter clusters on the observable properties of jets. We show that the intensity of jet radiation can give the possibility to observe such a phenomena and to probe the presence of dark matter subhaloes.
