Gravitational lensing is a powerful probe for understanding astrophysics and cosmology. Lensing is of particular use for constraining the expansion history of the Universe, since it is a geometric probe of the angular diameter distances between observer, lens, and source (Narayan 1991). When a time-variable source is multiply imaged by a gravitational lens, the time delays between images are inversely proportional to the Hubble constant H (Treu & Marshall 2016).
