    Euclid preparation: LXXI. Simulations and nonlinearities beyond ΛCDM. 3. Constraints on f(R) models from the photometric primary probes
    We study the constraint on f(R) gravity that can be obtained by photometric primary probes of the Euclid mission. Our focus is the dependence of the constraint...
  • Publication
    Euclid preparation: XLII. A unified catalogue-level reanalysis of weak lensing by galaxy clusters in five imaging surveys
    Precise and accurate mass calibration is required to exploit galaxy clusters as astrophysical and cosmological probes in the Euclid era. Systematic errors in...
  • Publication
    Euclid preparation: XLIV. Modelling spectroscopic clustering on mildly nonlinear scales in beyond-ΛCDM models
    Context. The Euclid space satellite mission will measure the large-scale clustering of galaxies at an unprecedented precision, providing a unique probe of...
  • Publication
    Euclid preparation: XLVI. The near-infrared background dipole experiment with Euclid
    Verifying the fully kinematic nature of the long-known cosmic microwave background (CMB) dipole is of fundamental importance in cosmology. In the standard...

    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: Constraining linearly scale-independent modifications of gravity with the spectroscopic and photometric primary probes
    Context. The future Euclid space satellite mission will offer an invaluable opportunity to constrain modifications to Einstein's general relativity at cosmic...

    Euclid: Cosmological forecasts from the void size function
    The Euclid mission - with its spectroscopic galaxy survey covering a sky area over 15 000 deg 2 in the redshift range 0.9 < z < 1.8 - will provide a sample of...

    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: Early Release Observations – A preview of the Euclid era through a galaxy cluster magnifying lens
    We present the first analysis of the Euclid Early Release Observations (ERO) program that targets fields around two lensing clusters, Abell 2390 and Abell 2764...
