Do active galactic nuclei convert dark matter into visible particles?

摘要

The hypothesis that dark matter consists of superheavy particles with themass close to the Grand Unification scale is investigated. These particles werecreated from vacuum by the gravitation of the expanding Universe and theirdecay led to the observable baryon charge. Some part of these particles withthe lifetime larger than the time of breaking of the Grand Unification symmetrybecame metastable and survived up to the modern time as dark matter. However inactive galactic nuclei due to large energies of dark matter particles swallowedby the black hole the opposite process can occur. Dark matter particles becomeinteracting. Their decay on visible particles at the Grand Unification energiesleads to the flow of ultra high energy cosmic rays observed by the Auger group.Numerical estimates of the effect leading to the observable numbers are given.
