The cosmic distance duality relation in light of the time-delayed strong gravitational lensing
Li Tang, Hai-Nan Lin, Ying Wu
The cosmic distance duality relation (DDR), which links the angular diameter distance and the luminosity distance, is a cornerstone in modern cosmology. Any deviation from DDR may…
