Time-delay Cosmography: Increased Leverage with Angular Diameter Distances
Inh Jee, Eiichiro Komatsu, Sherry H. Suyu +1
Strong lensing time-delay systems constrain cosmological parameters via the so-called time-delay distance and the angular diameter distance to the lens. In previous studies, only t…
