Gaussianity of Cosmic Velocity Fields and Linearity of the Velocity-Gravity Relation
Pawel Ciecielag, Michal Chodorowski, Marcin Kiraga +3
We present a numerical study of the relation between the cosmic peculiar velocity field and the gravitational acceleration field. We show that on mildly non-linear scales (4-10 Mpc…
Reconstructing Cosmic Peculiar Velocities from the Mildly Nonlinear Density Field
Andrzej Kudlicki, Michal Chodorowski, Tomasz Plewa +1
We present a numerical study of the cosmic density vs. velocity divergence relation (DVDR) in the mildly non-linear regime. We approximate the dark matter as a non-relativistic pre…
Nonlinearity and stochasticity in the density--velocity relation
F. Bernardeau, M. J. Chodorowski, E. L. Lokas +2
We present results of the investigations of the statistical properties of a joint density and velocity divergence probability distribution function (PDF) in the mildly non-linear r…
CPPA -- a New Hydrodynamical Code for Cosmological Large-Scale Structure Simulations
A. Kudlicki, T. Plewa, M. Rozyczka
We present a new Eulerian code able to follow the evolution of large-scale structures in the Universe in the weakly nonlinear regime. We compare test results with a N-body code and…
