    In order to find observable indications for Dark Matter (DM) some possible forms of DM from DM particles (WIMP) to DM planets in the solar system are considered. In particular, a compact DM planet on a specific orbit in the solar system is predicted to be a trigger for the solar dynamo with the 11-year cyclic activity of the Sun. Moreover, gravitational interaction of this compact DM planet...

  4. 18. Results of the Neutrino-4 experiment, sterile neutrinos, dark matter and the Standard Model

    Gravitation & Cosmology

    Joint analysis of the results of the Neutrino-4 experiment and the data of the GALLEX, SAGE and BEST experiments confirms the parameters of neutrino oscillations declared by the Neutrino-4 experiment (Δm_14^2= 7.3 eV^2 and sin^2〖2θ_14 〗≈0.36) and increases the confidence level to 5.8σ. Such a sterile neutrino thermalizes in cosmic plasma, contributes 5% to the energy density of the Universe,...

  5. 19. On a possible explanation of dark matter by means of a gluonic Bose-Einstein condensate in an anti-de Sitter geometry

    Gravitation & Cosmology

    The ΛCDM standard model of cosmology involves two dark components of the universe, dark energy, and dark matter. Whereas dark energy is usually associated with the (positive) cosmological constant Λ associated with a de Sitter geometry, we propose to explain dark matter as a pure QCD effect, namely a gluonic Bose Einstein condensate with the statusof a Cosmic Gluonic Background (CGB). This...

  6. 20. Mutual dependence of a bosonic black hole with dark matter and explanation of asymptotically flat galaxy rotation curves.

    Gravitation & Cosmology

    Dark matter makes itself felt only due to the gravitational interaction. Quanta of ordinary matter in flat space are described by vector fields. Let us assume that the wave function of dark matter quanta is also a vector field. Then it makes sense to find such a vector field in the general theory of relativity, which manifests itself exclusively in curved space-time...(see other details in the...

  7. 21. A class of rotating metrics in the presence of a scalar field
    Проф. Behrouz Mirza (Isfahan Technical University)

    Gravitation & Cosmology

    A class of three parameter metrics can be considered as a generalized form of a scalar field. The rotating form of the class of metrics can be obtained. The rotating JNW metric can be derived by choosing certain values of the parameters. Using the Harrison transformation one may derive charged form of the exact solutions.
