The observed presence of dark energy may be the first sign of new physics in the Universe, either in the form of a matter-energy component or by revising Einstein gravity. Weak gravitational lensing and galaxy peculiar velocities provide complementary probes of modifications to General Relativity, and in combination allow us to test theories of gravity in a unique way. We perform such an analysis by combining measurements of the growth of structure from the WiggleZ Dark Energy Survey with cosmic shear tomography from CFHTLenS, producing the best existing constraints on the metric potentials that describe general theories of gravity.
