PublicationEstimating the impact of recombination uncertainties on the cosmological parameter constraints from cosmic microwave background experiments
We use our most recent training set for the RICO code to estimate the impact of recombination uncertainties on the posterior probability distributions which...

PublicationEuclid preparation. VII. Forecast validation for Euclid cosmological probes
Aims: The Euclid space telescope will measure the shapes and redshifts of galaxies to reconstruct the expansion history of the Universe and the growth of cosmic...

PublicationEuclid preparation. XII. Optimizing the photometric sample of the Euclid survey for galaxy clustering and galaxy-galaxy lensing analyses
Photometric redshifts (photo-zs) are one of the main ingredients in the analysis of cosmological probes. Their accuracy particularly affects the results of the...

PublicationEuclid preparation. XIX. Impact of magnification on photometric galaxy clustering
Aims: We investigate the importance of lensing magnification for estimates of galaxy clustering and its cross-correlation with shear for the photometric sample...

PublicationEuclid preparation. XXVIII. Forecasts for ten different higher-order weak lensing statistics
Recent cosmic shear studies have shown that higher-order statistics (HOS) developed by independent teams now outperform standard two-point estimators in terms...

PublicationEuclid preparation. XXXIV. The effect of linear redshift-space distortions in photometric galaxy clustering and its cross-correlation with cosmic shear
Context. The cosmological surveys that are planned for the current decade will provide us with unparalleled observations of the distribution of galaxies on...

PublicationEuclid preparation. XXXV. Covariance model validation for the two-point correlation function of galaxy clusters
Aims: We validate a semi-analytical model for the covariance of the real-space two-point correlation function of galaxy clusters. Methods: Using 1000 PINOCCHIO...

PublicationEuclid preparation. XXXVI. Modelling the weak lensing angular power spectrum
This work considers which higher order modeling effects on the cosmic shear angular power spectra must be taken into account for Euclid. We identified the...
