The observable E_g statistics

Recently it has been shown that the E_g statistics, useful to test theories of modified gravity, is plagued by additional scale and bias dependent lensing contributions. In this work we develop and illustrate a method to remove these lensing terms by using in addition to the galaxy clustering data also shear data and the correlations of shear and galaxy clustering. I will be talking about this particular statistics, and our proposition about making it truly observable. I will also discuss what results this method gives for the Dark Energy Survey and Euclid.
