    Euclid 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...

    Euclid 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...

    Euclid 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...

    Euclid preparation: L. Calibration of the halo linear bias in Λ(v)CDM cosmologies
    The Euclid mission, designed to map the geometry of the dark Universe, presents an unprecedented opportunity for advancing our understanding of the cosmos...

    Euclid: Constraining dark energy coupled to electromagnetism using astrophysical and laboratory data
    In physically realistic, scalar-field-based dynamical dark energy models (including, e.g., quintessence), one naturally expects the scalar field to couple to...

    Euclid: Cosmology forecasts from the void-galaxy cross-correlation function with reconstruction
    We have investigated the cosmological constraints that can be expected from measurement of the cross-correlation of galaxies with cosmic voids identified in the...

    Euclid: Forecasts from redshift-space distortions and the Alcock-Paczynski test with cosmic voids
    Euclid is poised to survey galaxies across a cosmological volume of unprecedented size, providing observations of more than a billion objects distributed over a...

    Euclid: Forecasts from the void-lensing cross-correlation
    The Euclid space telescope will survey a large dataset of cosmic voids traced by dense samples of galaxies. In this work we estimate its expected performance...

    Euclid: Testing the Copernican principle with next-generation surveys
    Context. The Copernican principle, the notion that we are not at a special location in the Universe, is one of the cornerstones of modern cosmology. Its...
