# Evolution of one-point distributions from Gaussian initial fluctuations

@article{Kofman1994EvolutionOO, title={Evolution of one-point distributions from Gaussian initial fluctuations}, author={Lev Kofman and Edmund Bertschinger and James M. Gelb and Adi Nusser and Avishai Dekel}, journal={The Astrophysical Journal}, year={1994}, volume={420}, pages={44-57} }

We study the quasilinear evolution of the one-point probability density functions (PDFs) of the smoothed density and velocity fields in a cosmological gravitating system beginning with Gaussian initial fluctuations. Our analytic results are based on the Zel'dovich approximation and laminar flow. A numerical analysis extends the results into the multistreaming regime using the smoothed fields of a CDM N-body simulation. We find that the PDF of velocity, both Lagrangian and Eulerian, remains…
