Euclid preparation: LII. Forecast impact of super-sample covariance on 3×2pt analysis with Euclid
Context. Deviations from Gaussianity in the distribution of the fields probed by large-scale structure surveys generate additional terms in the data covariance matrix, increasing the uncertainties in the measurement of the cosmological parameters. Super-sample covariance (SSC) is among the largest of these non-Gaussian contributions, with the
Euclid Collaboration et al.
