IA/U.Lisboa Seminar - Higher-order statistics of weak lensing fields - 8 março 2018

Weak lensing has emerged as one of the most promising tool to constrain cosmological parameters and modified gravity theories by measuring second order statistical probes such as the cosmic shear two points correlation function and tomographic power spectra. Thanks to both the wide area and large redshift range probed, future surveys will deliver such an exquisite quality dataset that it is worth wondering whether one can move to higher-order statistics. We review here some interesting possibilities showing that they can be recovered with sufficient precision from future data and shed further light on the dark energy mystery.
