Cosmic microwave background bispectrum on small angular scales
Cyril Pitrou, Jean-Philippe Uzan, Francis Bernardeau
This article investigates the non-linear evolution of cosmological perturbations on sub-Hubble scales in order to evaluate the unavoidable deviations from Gaussianity that arise fr…
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…
Propagators in Lagrangian space
Francis Bernardeau, Patrick Valageas
It has been found recently that propagators, e.g. the cross-correlation spectra of the cosmic fields with the initial density field, decay exponentially at large-k in an Eulerian d…
