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…

Euclid preparation. Modelling spectroscopic clustering on mildly nonlinear scales in beyond-CDM models

Euclid Collaboration, B. Bose, P. Carrilho +229

We investigate the approximations needed to efficiently predict the large-scale clustering of matter and dark matter halos in beyond-CDM scenarios. We examine the normal branch…

Euclid preparation. LII. Forecast impact of super-sample covariance on 3x2pt analysis with Euclid

Euclid Collaboration, D. Sciotti, S. Gouyou Beauchamps +221

Deviations from Gaussianity in the distribution of the fields probed by large-scale structure surveys generate additional terms in the data covariance matrix, increasing the uncert…

Perturbation theory challenge for cosmological parameters estimation II.: Matter power spectrum in redshift space

Ken Osato, Takahiro Nishimichi, Atsushi Taruya +1

Constraining cosmological parameters from large-scale structure observations requires precise and accurate tools to compute its properties. While perturbation theory (PT) approache…

Euclid preparation: XXVIII. Modelling of the weak lensing angular power spectrum

Euclid Collaboration, A. C. Deshpande, T. Kitching +200

This work considers which higher-order effects in modelling the cosmic shear angular power spectra must be taken into account for Euclid. We identify which terms are of concern, an…

Euclid preparation. XXX. Performance assessment of the NISP Red-Grism through spectroscopic simulations for the Wide and Deep surveys

Euclid Collaboration, L. Gabarra, C. Mancini +232

This work focuses on the pilot run of a simulation campaign aimed at investigating the spectroscopic capabilities of the Euclid Near-Infrared Spectrometer and Photometer (NISP), in…
