In this paper, a cosmological model is considered, in which dark matter isemitted by T-symmetric quasi-black holes distributed over galaxies. Low energyphotons and neutrinos are taken as candidates for dark matter particles. Photoncase can be closed due to the suppression of electromagnetic waves byinterstellar/intergalactic medium. For neutrinos, two scenarios are considered.In the first, light neutrinos pair to bosonic quasiparticles that form massivehalos around galaxies. In the second, heavier sterile neutrinos form massivehalos without pairing. At the observables level, both scenarios turn out to beequivalent to the standard LambdaCDM model. At the same time, the consideredmodel possesses additional sources -- quasi-black holes -- that can produce therequired number of neutrinos in addition to the Big Bang. This opens upadditional possibilities for cosmological constructions. The matching of themodel with early cosmology and ongoing neutrino experiments is discussed. Inaddition, the possibility of solving general cosmological problems, includinghorizon, flatness and cosmological constant problems, as well as Hubbletension, within the framework of the considered model, is discussed.
