Abstract content
The recent 'microscopic' theory of black holes (Ter-Kazarian, G.T. 2001, J. Phys.
Soc. Jpn., Suppl., B 70, 84; and references therein) predicts a large flux of
extremely high energy. They are produced thermally by the predominant
neutrino cooling of the superdense proto-matter core (SPC) of AGN via simple
or "modified" URCA processes, and pionic reactions. We calculate the neutrino
fluxes emitted from probable 234 AGN black holes, with the well-determined
masses and bolometric luminosities collected from the literature.
The derived EHE neutrino fluxes are in good agreement with the results
presented in literature. We also study the time evolution of spectrum
of neutrinos of both the fueling at accretion onto SPC and its neutrino
cooling. The part of these neutrinos would be lost in the accretion
disk and in a torus of hot gas surrounding the SPC to produce, further, the
secondary EHE electrons, which, in turn, through well-known relevant
processes of pair-production, inverse Compton scattering and synchrotron
radiation may give rise a secondary flux of the gamma-rays (GRs).
Therefore, the extra-galactic sources- the AGNs, can be strong
EHE neutrino and GR emitters.
