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…
Constraining Primordial non-Gaussianity with Bispectrum and Power Spectum from Upcoming Optical and Radio Surveys
Dionysios Karagiannis, Andrei Lazanu, Michele Liguori +3
We forecast constraints on primordial non-Gaussianity (PNG) and bias parameters from measurements of galaxy power spectrum and bispectrum in future radio continuum and optical surv…
