The accelerating expansion of the universe is one of the most mysterious phenomena. The cosmic acceleration implies existence of dark energy or breakdown of Einstein’s general relativity. Either way, revealing the source of cosmic acceleration can result in a paradigm shift in the field of modern physics. Weak gravitational lensing is small, coherent distortion of distant galaxy images due to gravitational potential, which allows the direct measurement of dark matter spatial distributions. Weak lensing is one of the most powerful …
