Dark Energy Survey Year 3 results: cosmology with moments of weak lensing mass maps -- validation on simulations

Understand

We present a simulated cosmology analysis using the second and third moments of the weak lensing mass (convergence) maps.

• The analysis is geared towards the third year (Y3) data from the Dark Energy Survey (DES), but the methodology can be applied to other weak lensing data sets.
• The second moment, or variances, of the convergence as a function of smoothing scale contains information similar to standard shear 2-point statistics.
• The third moment, or the skewness, contains additional non-Gaussian information.
