    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...

    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...
