Euclid: The reduced shear approximation and magnification bias for Stage IV cosmic shear experiments
A. C. Deshpande, T. D. Kitching, V. F. Cardone +69
Stage IV weak lensing experiments will offer more than an order of magnitude leap in precision. We must therefore ensure that our analyses remain accurate in this new era. Accordin…
Euclid preparation: VI. Verifying the Performance of Cosmic Shear Experiments
Euclid Collaboration, P. Paykari, T. D. Kitching +128
Our aim is to quantify the impact of systematic effects on the inference of cosmological parameters from cosmic shear. We present an end-to-end approach that introduces sources of…
Euclid preparation: VII. Forecast validation for Euclid cosmological probes
Euclid Collaboration, A. Blanchard, S. Camera +151
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 structures. Estimation of…
Euclid: Reconstruction of Weak Lensing mass maps for non-Gaussianity studies
S. Pires, V. Vandenbussche, V. Kansal +43
Weak lensing, which is the deflection of light by matter along the line of sight, has proven to be an efficient method for constraining models of structure formation and reveal the…
Euclid preparation: V. Predicted yield of redshift 7<z<9 quasars from the wide survey
Euclid Collaboration, R. Barnett, S. J. Warren +126
We provide predictions of the yield of quasars from the Euclid wide survey, updating the calculation presented in the Euclid Red Book in several ways. We account for revisi…
Euclid preparation III. Galaxy cluster detection in the wide photometric survey, performance and algorithm selection
Euclid Collaboration, R. Adam, M. Vannier +56
Galaxy cluster counts in bins of mass and redshift have been shown to be a competitive probe to test cosmological models. This method requires an efficient blind detection of clust…
Euclid: Nonparametric point spread function field recovery through interpolation on a graph Laplacian
M. A. Schmitz, J. -L. Starck, F. Ngole Mboula +35
Context. Future weak lensing surveys, such as the Euclid mission, will attempt to measure the shapes of billions of galaxies in order to derive cosmological information. These surv…
Euclid Preparation IV. Impact of undetected galaxies on weak-lensing shear measurements
Euclid Collaboration, N. Martinet, T. Schrabback +22
In modern weak-lensing surveys, the common approach to correct for residual systematic biases in the shear is to calibrate shape measurement algorithms using simulations. These sim…
