A cosmographic analysis using DESI-DR2 and strong lensing: I. Time-Delay measurements
Darshan Kumar, Deepak Jain, Shobhit Mahajan
Strong gravitational lensing time-delay measurements, together with the distance sum rule (DSR), offer a model-independent approach to probe the geometry and expansion of the unive…
