Scientific paper

We propose a novel scenario for the formation and time evolution of dark matter balls composed of degenerate, self-gravitating tau -neutrinos and antineutrinos. This model is based on the interplay of two competing processes: annihilation of the particle-antiparticle pairs via weak interaction and spherical (Bondi) accretion of these particles. Our model can account for the formation of dark matter balls, which could play a role similar to that of supermassive (~109 M&sun;) black holes in active galactic nuclei if the neutrino mass is in the range 10-25 keV/c2.
