CURLING -- II. Improvement on the Inference from Pixelized Cluster Strong Lens Modeling
Yushan Xie, Huanyuan Shan, Yiping Shu +9
Strongly lensed supernovae (glSNe) provide a powerful, independent method to measure the Hubble constant, , through time delays between their multiple images. The accuracy o…
Impact of Large-Scale Structure along Line-of-Sight on Time-Delay Cosmography
Shijie Lin, Bin Hu, Chengliang Wei +4
Time-delay cosmography, by monitoring the multiply imaged gravitational lenses in the time domain, offers a promising and independent method for measuring cosmological distances. H…
Discovery of a Low-mass Strong-lens System in SMACS J0723.3-7327
Limeng Deng, Yiping Shu, Lei Wang +6
We report the discovery of an intriguing, low-mass galaxy-scale strong-lens system in the SMACS J0723.3-7327 galaxy cluster. By modeling James Webb Space Telescope imaging and Very…
Discovery of 19 strongly-lensed quasars, dual and projected quasars in DESI-LS
Zizhao He, Qihang Chen, Limeng Deng +5
We report the follow-up spectroscopic confirmation of two lensed quasars, six dual quasars, and eleven projected quasars that were previously identified as lensed-quasar candidates…
Forecast of gravitationally lensed Type Ia supernovae time delay measurement by Muztage-Ata 1.93m Synergy Telescope
Guanhua Rui, Wenwen Zheng, Zizhao He +4
Strong lensing time delay measurement is a promising method to address the Hubble tension, offering a completely independent approach compared to both the cosmic microwave backgrou…
Using Convolutional Neural Networks to Search for Strongly Lensed Quasars in KiDS DR5
Zizhao He, Rui Li, Yiping Shu +13
Gravitationally strongly lensed quasars (SL-QSO) offer invaluable insights into cosmological and astrophysical phenomena. With the data from ongoing and next-generation surveys, th…
