Modeling of weak lensing statistics. II. Configuration-space statistics

Understand

We investigate the performance of an analytic model of the 3D matter distribution, which combines perturbation theory with halo models, for weak-lensing configuration-space statistics.

• We compared our predictions for the weak-lensing convergence two-point and three-point correlation functions with numerical simulations and fitting formulas proposed in previous works.
• We also considered the second- and third-order moments of the smoothed convergence and of the aperture-mass.
• As in our previous study of Fourier-space weak-lensing statistics, we find that our model agrees better with simulations than previously published fitting formulas.
