A fitting formula for the non‐linear evolution of the bispectrum
/ Authors
/ Abstract
ABSTRA C T We present a fitting formula for the non-linear evolution of the bispectrum in cold dark matter (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.
