Lensed Quasar Search in Imaging Surveys

Gravitationally lensed quasars are valuable astronomical objects that offer unique opportunities for studying galaxy evolution and cosmology. Current and upcoming imaging surveys will contain thousands of new lensed quasars, augmenting the existing sample by an order of magnitude. We report the discovery of new lensed quasars (or candidates) in the HSC and CFIS surveys. Spectroscopic or high-resolution imaging follow up on these newly discovered lensed quasar candidates will further allow their natures to be confirmed.
