Multi-Point Propagators in Cosmological Gravitational Instability
Francis Bernardeau, Martin Crocce, Roman Scoccimarro
We introduce the concept of multi-point propagators between linear cosmic fields and their nonlinear counterparts in the context of cosmological perturbation theory. Such functions…
Nonlinear Evolution of Baryon Acoustic Oscillations
M. Crocce, R. Scoccimarro
We study the nonlinear evolution of the baryon acoustic oscillations (BAO) in the dark matter power spectrum and correlation function using renormalized perturbation theory (RPT).…
Transients from Initial Conditions in Cosmological Simulations
M. Crocce, S. Pueblas, R. Scoccimarro
We study the impact of setting initial conditions in numerical simulations using the standard procedure based on the Zel'dovich approximation (ZA). As it is well known from perturb…
Cosmology and the Bispectrum
Emiliano Sefusatti, Martin Crocce, Sebastian Pueblas +1
The present spatial distribution of galaxies in the Universe is non-Gaussian, with 40% skewness in 50 Mpc/h spheres, and remarkably little is known about the information encoded in…
Memory of Initial Conditions in Gravitational Clustering
M. Crocce, R. Scoccimarro
We study the nonlinear propagator, a key ingredient in renormalized perturbation theory (RPT) that allows a well-controlled extension of perturbation theory into the nonlinear regi…
Renormalized Cosmological Perturbation Theory
M. Crocce, R. Scoccimarro
We develop a new formalism to study nonlinear evolution in the growth of large-scale structure, by following the dynamics of gravitational clustering as it builds up in time. This…
