Probing nonlinear structure formation beyond CDM with the LSS bootstrap: a joint power spectrum and bispectrum analysis
Giorgia Biselli, Marco Marinucci, Guido D'Amico +1
We present the first MCMC-derived constraints on the parameters of the Large Scale Structure (LSS) bootstrap, a model-independent framework that captures deviations from CDM us…

Constraints on dark energy and modified gravity from the BOSS Full-Shape and DESI BAO data
Petter Taule, Marco Marinucci, Giorgia Biselli +2
We constrain dark energy and modified gravity within the effective field theory of dark energy framework using the full-shape BOSS galaxy power spectrum, combined with Planck cosmi…
