Abstract
We address the amount of information in the non-Gaussian regime of weak lensing surveys by modelling all relevant covariances of the power spectra and bispectra, using 1000 ray-tracing simulation realizations for a Λcold dark matter (ΛCDM) model and an analytical halo model. We develop a formalism to describe the covariance matrices of po...More
