The Ω dependence of the velocity divergence distribution

Analytical studies based on perturbative theory have shown that the moments of the Probability Distribution Function (PDF) of the local smoothed velocity divergence are expected to have a very specific dependence on the density parameter Ω in the quasilinear regime. This dependence is particularly interesting as it does not involve the possible bias between the galaxy spatial distribution and t...

The Omega dependence of the velocity divergence distribution

We present a series of results investigating the Ω dependence of the distribution function of the large scale local cosmic velocity divergence, ∇ · v. Analytical studies using perturbation theory techniques indicate that the shape of this distribution should be strongly dependent on Ω. This dependence is all the more interesting as it does not involve biases of the galaxy distribution with resp...

Cosmological Perturbation Theory and the Spherical Collapse model - III . The Velocity divergence field & the Ω - dependence

Cosmological Perturbation Theory (PT) is a useful tool to study the cumulants of the density and velocity fields in the large scale structure of the Universe. In papers I & II of this series we saw that the Spherical Collapse (SC) model provides with the exact solution to PT at tree-level and gives a good approximation to the loop corrections (next to leading orders), indicating negligible tida...
