On the Relation Between Field-Level Posteriors, Correlators, and their Likelihoods
Massimo Pietroni, Fabian Schmidt
We develop a field-level posterior for cosmological data by marginalizing over initial conditions and noise in a general forward model. While our focus is on large-scale structure…
(1+1)-Dimensional Schrödinger-Poisson equation with contact interaction
Óscar Rodríguez-Villalba, Ivan Saychenko, Massimo Pietroni +1
We investigate the role of contact interactions in the dynamics of fuzzy dark matter (FDM) modeled through the Schrödinger-Poisson equation in one spatial dimension. While the C…
Renormalized Perturbation Theory at Field-level: the LSS bootstrap in GridSPT
Matteo Peron, Takahiro Nishimichi, Massimo Pietroni +1
We present a first step toward field-level cosmological inference beyond the standard CDM model, focusing on optimizing precision tests in the nonlinear regime of large-scale st…
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…
Bootstrapping Lagrangian Perturbation Theory for the Large Scale Structure
Marco Marinucci, Kevin Pardede, Massimo Pietroni
We develop a model-independent approach to lagrangian perturbation theory for the large scale structure of the universe. We focus on the displacement field for dark matter particle…
Constraining Primordial Non-Gaussianity from Large Scale Structure with the Wavelet Scattering Transform
Matteo Peron, Gabriel Jung, Michele Liguori +1
We investigate the Wavelet Scattering Transform (WST) as a tool for the study of Primordial non-Gaussianity (PNG) in Large Scale Structure (LSS), and compare its performance with t…
