Scientific paper

After the discovery of quasars, theories of active galactic nuclei (AGN) were constructed which focused on the investigation of gas dynamics in the gravitational potential of a black hole. In this paper we study the influence of a possible dark matter neutrino ball on the accretion process in AGN, and investigate possible observable signatures of such a ball which is supported by degeneracy pressure. We find that, if such balls exist in the vicinity of AGN, they will cause a bump in the IR region of the emitted spectrum which is, in fact, observed for several AGN. We also find that, if the bump corresponding to ~1000K in the spectrum of the typical radio-loud quasar 3C273 is due to a neutrino ball, then our model implies a mass of the black hole of 10^8 M_solar, a ball mass of 4x10^9 M_solar and in turn, a neutrino of mass 3keV/c^2.
