Transients from Initial Conditions: A Perturbative Analysis
Roman Scoccimarro
The standard procedure to generate initial conditions (IC) in numerical simulations is to use the Zel'dovich approximation (ZA). Although the ZA correctly reproduces the linear gro…

Non-Linear Evolution of the Bispectrum of Cosmological Perturbations
Roman Scoccimarro, Stephane Colombi, J. N. Fry +3
The bispectrum, the three-point function of density fluctuations in Fourier space, is the lowest order statistic that carries information about the spatial coherence of large-scale…

Understanding Gravitational Clustering with Non-Linear Perturbation Theory
Roman Scoccimarro
I discuss new results concerning the evolution of the bispectrum due to gravitational instability from gaussian initial conditions using one-loop perturbation theory (PT). Particul…
