Findings

Algorithms successfully produce weak lensing maps in screened theories.

Basic statistics can differentiate these theories from general relativity.

Tools enable mock survey generation for cosmological tests.

Abstract

A number of alternatives to general relativity exhibit gravitational screening in the non-linear regime of structure formation. We describe a set of algorithms that can produce weak lensing maps of large scale structure in such theories and can be used to generate mock surveys for cosmological analysis. By analysing a few basic statistics we indicate how these alternatives can be distinguished from general relativity with future weak lensing surveys.
