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…
Detecting the relativistic galaxy bispectrum
Roy Maartens, Sheean Jolicoeur, Obinna Umeh +3
The Fourier-space galaxy bispectrum is complex, with the imaginary part arising from leading-order relativistic corrections, due to Doppler, gravitational redshift and related line…
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 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…
Searching for gamma-ray emission from galaxy clusters at low redshift
Manuel Colavincenzo, Xiuhui Tan, Simone Ammazzalorso +4
We report the identification of a positive cross-correlation signal between the unresolved -ray emission, measured by the \emph{Fermi} Large Area Telescope, and four different g…
