The gravitational field of the large scale structure in the Universe deflects light rays travelling through the Universe. This induces coherent distortions in the shapes of distant galaxies.
We call this regime within the gravitational lensing phenomena: cosmic shear. The entire mass, be it luminous or dark, contributes to the weak gravitational lensing effect. So, by measuring the shapes of these distant galaxies we can study the total matter distribution in the Universe. During my ta …
