    Estimating the impact of recombination uncertainties on the cosmological parameter constraints from cosmic microwave background experiments
    We use our most recent training set for the RICO code to estimate the impact of recombination uncertainties on the posterior probability distributions which...

    Euclid and KiDS-1000: Quantifying the impact of source-lens clustering on cosmic shear analyses
    Cosmic shear is a powerful probe of cosmological models and the transition from current Stage-III surveys such as the Kilo-Degree Survey (KiDS) to the increased...

    Euclid preparation. XIII. Forecasts for galaxy morphology with the Euclid Survey using deep generative models
    We present a machine learning framework to simulate realistic galaxies for the Euclid Survey, producing more complex and realistic galaxies than the analytical...

    Euclid preparation. XIX. Impact of magnification on photometric galaxy clustering
    Aims: We investigate the importance of lensing magnification for estimates of galaxy clustering and its cross-correlation with shear for the photometric sample...
