  • Future large ensembles of time delay (TD) lenses have the potential to provide interesting cosmological constraints complementary to those of other methods. In a flat universe with constant w including a Planck prior, The Large Synoptic Survey Telescope TD measurements for ~4000 lenses should constrain the local Hubble constant h to ~0.007 (~1%), ? de to ~0.005, and w to ~0.026 (all 1? precisions). Similar constraints could be obtained by a dedicated gravitational lens observatory (OMEGA) which… CONTINUE READING
