Robo-AO Survey Programs - Lensed Quasars By observing lensed quasars, we can model the mass distribution within a galaxy: tells us about the dark matter distribution Currently there are ~100 known lenses, and 10,000++ known candidates Using Robo-AO and a few months of observing we can expand the number of known lenses by factor of 10 or more Follow up for time delays / dynamics Einstein Cross (HST) (1.6 arc sec top to bottom)
