Euclid preparation: The flat-sky approximation for the clustering of Euclid's photometric galaxies

Euclid Collaboration, W. L. Matthewson, R. Durrer +277

We compare the performance of the flat-sky approximation and Limber approximation for the clustering analysis of the photometric galaxy catalogue of Euclid. We study a 6 bin config…

Euclid preparation. Full-shape modelling of 2-point and 3-point correlation functions in real space

Euclid Collaboration, M. Guidi, A. Veropalumbo +308

We investigate the accuracy and range of validity of the perturbative model for the 2-point (2PCF) and 3-point (3PCF) correlation functions in real space in view of the forthcoming…

Euclid preparation. LIX. Angular power spectra from discrete observations

Euclid Collaboration, N. Tessore, B. Joachimi +266

We present the framework for measuring angular power spectra in the Euclid mission. The observables in galaxy surveys, such as galaxy clustering and cosmic shear, are not continuou…
