Cosmological parameters from combined second- and third-order aperture mass statistics of cosmic shear

Cosmological parameters from combined second- and third-order aperture mass statistics of cosmic shear

We present predictions for cosmological parameter constraints from combined measurements of second- and third-order statistics of cosmic shear. We define the generalized third-order aperture mass statistics and show that it contains much more information about the bispectrum of the projected matter density than the skewness of the aperture mass. From …
