A Fitting Formula for the Non-Linear Evolution of the Bispectrum

Astrophysics 2009-10-31 v1

Abstract

We present a fitting formula for the non-linear evolution of the bispectrum in CDM models, obtained from measurements in high resolution numerical simulations. The formula interpolates between the perturbative and highly non-linear regimes, and generalizes previous results obtained for scale-free initial conditions.
