Ellipsoidal collapse and the redshift space probability distribution function of dark matter
Tsz Yan Lam, Ravi K. Sheth
We use the physics of ellipsoidal collapse to model the probability distribution function of the smoothed dark matter density field in real and redshift space. We provide a simple…

Perturbation theory and excursion set estimates of the probability distribution function of dark matter, and a method for reconstructing the initial distribution function
T. Y. Lam, R. K. Sheth
Nonlinear evolution can sometimes be modelled by a deterministic mapping from initial to final of the local smoothed overdensity. Perturbation theory methods base on this determini…
