Optimal marked statistics from the Effective Field Theory of Large Scale Structure
Marco Marinucci, Michele Liguori, Federico Semenzato +1
We present a simple and robust framework to assess the information content of the power spectrum of a marked density field within the Effective Field Theory of Large Scale Structur…
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…
Field-Level Inference of Primordial Non-Gaussianity with the Quijote Simulation Suite
Adam Andrews, Jens Jasche, Guilhem Lavaux +10
Local primordial non-Gaussianity, parameterised as , will be stringently constrained using state-of-the-art methods applied to next-generation galaxy redshi…
Euclid preparation. Review of forecast constraints on dark energy and modified gravity
Euclid Collaboration, N. Frusciante, M. Martinelli +326
The Euclid mission has been designed to provide, as one of its main deliverables, information on the nature of the gravitational interaction, which determines the expansion of the…
Euclid preparation. XLI. Galaxy power spectrum modelling in real space
Euclid Collaboration, A. Pezzotta, C. Moretti +246
We investigate the accuracy of the perturbative galaxy bias expansion in view of the forthcoming analysis of the Euclid spectroscopic galaxy samples. We compare the performance of…
Equivalence of the field-level inference and conventional analyses on large scales
Francesco Spezzati, Marco Marinucci, Marko SimonoviÄ
We study a simple setup with dark matter halos in real space, with the amplitude of the linear density field as the only free cosmological parameter. We show that Eulerian pert…
