    Euclid preparation. XXVIII. Forecasts for ten different higher-order weak lensing statistics
    Recent cosmic shear studies have shown that higher-order statistics (HOS) developed by independent teams now outperform standard two-point estimators in terms...
  • Publication
    Euclid preparation. XXXIII. Characterization of convolutional neural networks for the identification of galaxy-galaxy strong-lensing events
    Forthcoming imaging surveys will increase the number of known galaxy-scale strong lenses by several orders of magnitude. For this to happen, images of billions...

    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: XLV. Optical emission-line predictions of intermediate-z galaxy populations in GAEA for the Euclid Deep and Wide Surveys
    In anticipation of the upcoming Euclid Wide and Deep Surveys, we present optical emission-line predictions at intermediate redshifts from 0.4 to 2.5. Our...

    Euclid: Calibrating photometric redshifts with spectroscopic cross-correlations
    Cosmological constraints from key probes of the Euclid imaging survey rely critically on the accurate determination of the true redshift distributions, n(z), of...
  • Publication
    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 ensemble photometric redshift distributions with stacked spectroscopy
    Context. The ESA Euclid mission will produce photometric galaxy samples over 15 000 square degrees of the sky that will be rich for clustering and weak lensing...
  • Publication
    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...
