Large-scale bulk motion and dark matter

  • D. J. Song


In the universe dominated by massive neutrino dark matter we calculated the peculiar velocity and compared this with the large-scale bulk motion. The constraints on parameters of the universe, such as the index of density fluctuation spectrum and density contrast of large-scale structure, cosmological density parameter and Hubble parameter, and mass and degeneracy parameter of the dark-matter component, were discussed. The dependence of the window function was also discussed.
