K-mouflage Imprints on Cosmological Observables and Data Constraints
Giampaolo Benevento, Marco Raveri, Andrei Lazanu +4
We investigate cosmological constraints on K-mouflage models of modified gravity. We consider two scenarios: one where the background evolution is free to deviate from CDM (K-mo…
Modelling the matter bispectrum towards nonlinear scales - two and three loops in perturbation theories
Andrei Lazanu
I compute the matter bispectrum of large-scale structure up to two loops in the Standard Perturbation Theory and up to three loops in the MPTbreeze renormalised perturbation theory…
The two and three-loop matter bispectrum in perturbation theories
Andrei Lazanu, Michele Liguori
We evaluate for the first time the dark matter bispectrum of large-scale structure at two loops in the Standard Perturbation Theory and at three loops in the Renormalised Perturbat…
Bispectrum Modelling in Large Scale Structure - A Three Shape Model
Andrei Lazanu
We study the matter bispectrum of large structure by comparing theoretical models (perturbation theories and halo models) to numerical simulations using shape and amplitude correla…
