Evolution of the Pairwise Peculiar Velocity Distribution Function in Lagrangian Perturbation Theory
The statistical distribution of the radial pairwise peculiar velocity of galaxies is known to have an exponential form as implied by observations and explicitly shown in N−body simulations. Here we calculate its statistical distribution function using the Zel’dovich approximation assuming that the primordial density fluctuations are Gaussian distributed. We show that the exponential distributio...
متن کاملPeculiar Velocity, Cosmic Perturbation Theory and the Cmb Anisotropy
It is proved that the cosmological density perturbation is associated with a peculiar velocity field. This allows a simple formulation of cosmological perturbation theory, which works entirely with quasi-Newtonian fluid flow equations. As an illustration, the large scale cosmic microwave background anisotropy (Sachs-Wolfe effect) is calculated without any reference to the metric perturbation. I...
متن کاملModeling Pairwise Peculiar Velocity Distribution Function of Dark Matter from Halo Density Profiles
We derive the pairwise peculiar velocity distribution function of dark matter particles applying the dark matter halo approach. Unlike the previous work, we do not assume a Gaussian velocity distribution function of dark matter in a single halo, but compute it self-consistently with the assumed density profile for dark matter halo. The resulting distribution function is well approximated by an ...
متن کاملExtending Lagrangian perturbation theory to a fluid with velocity dispersion
We formulate a perturbative approximation to gravitational instability, based on Lagrangian hydrodynamics in Newtonian cosmology. We take account of ‘pressure’ effect of fluid, which is kinematically caused by velocity dispersion, to aim hydrodynamical description beyond shell crossing. Master equations in the Lagrangian description are derived and solved perturbatively up to second order. Then...
متن کاملThe distribution of pairwise peculiar velocities in the nonlinear regime
The distribution of pairwise, relative peculiar velocities, f(u; r), on small nonlinear scales, r, is derived from the Press{Schechter approach. This derivation assumes that Press{Schechter clumps are virialized and isothermal. The virialized assumption requires that the circular velocity, Vc / M , where M denotes the mass of the clump. The isothermal assumption means that the circular velocity...
