Euclid preparation: XI. Mean redshift determination from galaxy redshift probabilities for cosmic shear tomography

Euclid Collaboration, O. Ilbert, S. de la Torre +162

The analysis of weak gravitational lensing in wide-field imaging surveys is considered to be a major cosmological probe of dark energy. Our capacity to constrain the dark energy eq…

Euclid: Forecast constraints on the cosmic distance duality relation with complementary external probes

M. Martinelli, C. J. A. P. Martins, S. Nesseris +82

In metric theories of gravity with photon number conservation, the luminosity and angular diameter distances are related via the Etherington relation, also known as the distance-du…

Euclid: The importance of galaxy clustering and weak lensing cross-correlations within the photometric Euclid survey

I. Tutusaus, M. Martinelli, V. F. Cardone +87

The data from the Euclid mission will enable the measurement of the photometric redshifts, angular positions, and weak lensing shapes for over a billion galaxies. This large datase…

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…

Cosmological information in the redshift-space bispectrum

Victoria Yankelevich, Cristiano Porciani

We use the Fisher-matrix formalism to investigate whether the galaxy bispectrum in redshift space, , contains additional cosmological information with respect to the power spect…
