Modelling Galaxy Clustering for the Euclid mission


IFPU
September 30 – October 4, 2019


This hands-on meeting brings together members of the Euclid Galaxy Clustering Science Working Group involved in the development and testing of theoretical models for the galaxy power spectrum and higher-order correlation functions. The main motivation for studying higher-order correlation functions of the large-scale structure – primarily the galaxy 3-point correlation function in configuration space and the bispectrum in Fourier space – resides in the fact that the galaxy distribution is a highly non-Gaussian random field, even at the largest scales that Euclid is expected to probe. These statistics are then needed to describe the filamentary nature of the galaxy and matter density distributions, as well as encode precious information on galaxy biasing, redshift-space distortions and the level of primordial non-Gaussianity. The Higher-Order Statistics Work Package is the team in charge of developing the tools for their analysis and exploitation within the Euclid Consortium. The group is already working on a number of interconnected projects and will take great advantage of the opportunity to carry out part of this effort in a common setting.
