    Euclid preparation. VIII. The Complete Calibration of the Colour-Redshift Relation survey: VLT/KMOS observations and data release
    The Complete Calibration of the Colour-Redshift Relation survey (C3R2) is a spectroscopic effort involving ESO and Keck facilities designed specifically to...
  • Publication
    Euclid preparation. X. The Euclid photometric-redshift challenge
    Forthcoming large photometric surveys for cosmology require precise and accurate photometric redshift (photo-z) measurements for the success of their main...
  • Publication
    Euclid preparation. XI. Mean redshift determination from galaxy redshift probabilities for cosmic shear tomography
    The analysis of weak gravitational lensing in wide-field imaging surveys is considered to be a major cosmological probe of dark energy. Our capacity to...
