Weak lensing cosmology beyond Gaussianity

Charlista: Daniela Grandón, Leiden

Resumen: Weak gravitational lensing is a powerful cosmological probe for decoding the imprints of dark energy and dark matter on large-scale structures. To constrain cosmological parameters from observations, it is crucial to develop estimators that capture the statistical properties of the weak lensing field. Since processes like the gravitational collapse introduce non-Gaussianities, estimators beyond the power spectrum are necessary to account for this additional information.
