    Euclid preparation. XXXI. The effect of the variations in photometric passbands on photometric-redshift accuracy
    The technique of photometric redshifts has become essential for the exploitation of multi-band extragalactic surveys. While the requirements on photometric...

    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: LIX. Angular power spectra from discrete observations
    In this paper we present the framework for measuring angular power spectra in the Euclid mission. The observables in galaxy surveys, such as galaxy clustering...

    Euclid preparation: LXI. Cosmic Dawn Survey: 'Pre-launch' multiwavelength catalogues for Euclid Deep Field North and Euclid Deep Field Fornax
    The Cosmic Dawn Survey (DAWN survey) provides multiwavelength (UV/optical to mid-IR) data across the combined 59 deg 2 of the Euclid Deep and Auxiliary fields...

    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...

    Euclid: A complete Einstein ring in NGC 6505
    We report the discovery of a complete Einstein ring around the elliptical galaxy NGC 6505, at z = 0.042. This is the first strong gravitational lens discovered...

    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: 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...
