We review progress in understanding dark matter by astrophysics, and particularly via the effect of gravitational lensing. Evidences from many different directions now all imply that five sixths of the material content of the Universe is in this mysterious form, separate from and beyond the ordinary ‘baryonic’ particles in the standard model of particle physics. Dark matter appears not to interact via the electromagnetic force, and therefore neither emits nor reflects light. However, it definitely does interact via gravity, and has played the most important role in shaping the Universe on large scales. The most successful technique with which to investigate it has so far been the effect of gravitational lensing. The curvature of space–time near any gravitating mass (including dark matter) deflects passing rays of light—observably shifting, distorting and magnifying the images of background galaxies. Measurements of such effects currently provide constraints on the mean density of dark matter, and its density relative to baryonic matter; the size and mass of individual dark matter particles and its cross-section under various fundamental forces.

Cosmological parameter constraints from galaxy-galaxy lensing and galaxy clustering with the SDSS DR7 (2012, background): “…of observing the total matter density (including dark matter), via the deflections of light due to intervening matter along the line-ofsight, which both magnifies and distorts galaxy shapes (for a review, see Bartelmann & Schneider 2001; Refregier 2003; Hoekstra & Jain 2008; Massey et al. 2010).”
The first-year shear catalog of the Subaru Hyper Suprime-Cam Subaru Strategic Program Survey (2017, background): “As a result, Bmode convergence fields (mass maps), which are produced by curl-like patterns in the shear field, are used to check for the presence of certain residual systematics in weak lensing shear catalogs (e.g., Massey et al. 2010).”
