Euclid 3rd Parma meeting

IFPU & Online
December 19 – 22, 2022

The upcoming Euclid mission will measure the Large Scale Structure of the Universe with unprecedented precision, yielding tight constraints on the cosmological parameters. Such measurements will provide the basis to test the consistency of the standard ΛCDM model of cosmology and its extensions, including massive neutrinos and evolving Dark Energy, as well as a variety of Modified Gravity models: this will allow to shed light on the mechanism behind the observed accelerated expansion of the Universe. In order to fully exploit the upcoming measurements of cosmological summary statistics, it is crucial to have a robust modelling for the non-linear regime of structure formation, where most of the information reside. The ”Parma meetings” are devoted to the development of the science of Work Package 7 of Euclid’s Theory Working Group, Analytical approaches to non-linearities. This includes the development of the appropriate non-linear recipes for several extended cosmological models, assessing the performance of possible approximations, and testing the selected models against a set of N-body simulations that implement several extended cosmological scenarios. This IFPU Focus week program is the perfect framework to advance these projects.
