Impact of Large-scale Structure along the Line of Sight on Time-delay Cosmography
Time-delay cosmography offers a promising and independent method for measuring cosmological distances by monitoring multiple images of gravitationally lensed sources. However, beyond the main deflector, large-scale structure along the line of sight (LoS) also deflects travelling light rays via weak lensing (WL). Due to...
