Structure Formation with Cold + Hot Dark Matter

  title={Structure Formation with Cold + Hot Dark Matter},
  author={Anatoly Klypin and Joel R. Primack and Enikő Regős},
We report results from high-resolution particle-mesh (PM) N-body simulations of structure formation in an Ω = 1 cosmological model with a mixture of Cold plus Hot Dark Matter (C+HDM) having Ω cold = 0.6, Ω ν = 0.3, and Ω baryon = 0.1. We present analytic fits to the C+HDM power spectra for both cold and hot (ν) components, which provide initial conditions for our nonlinear simulations. In order to sample the neutrino velocities adequately, these simulations included six times as many neutrino… CONTINUE READING
