    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. XXX. Performance assessment of the NISP red grism through spectroscopic simulations for the wide and deep surveys
    This work focusses on the pilot run of a simulation campaign aimed at investigating the spectroscopic capabilities of the Euclid Near-Infrared Spectrometer and...
  • Publication
    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...
  • 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...
  • 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...
