Weak lensing of large scale structure in the presence of screening

Understand

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.
