Discovery of a Strong-lens Galaxy Pair with the Smallest Projected Separation
Zizhao He, Limeng Deng, Qihang Chen +3
We present the spectroscopic confirmation and lens modeling of HSC~J02330205, a strong-lensing system produced by a close pair of elliptical galaxies at that…

CURLING -- III. Identifying Candidates of Wide-separation Gravitationally Lensed Quasars from the CatNorth Catalogue
Di Wu, Zizhao He, Nan Li +5
Wide-separation lensed quasars (WSLQs) are a rare subclass of strongly lensed quasars produced by massive galaxy clusters. They provide valuable probes of dark-matter halos and qua…

CSST Strong Lensing Preparation: Cosmological constraints from double-source-plane strong lensing systems in era of CSST
Bei-Chen Wu, Xiaoyue Cao, Nan Li +5
Double source plane strong lensing (DSPL) systems offer a robust, independent probe of cosmological parameters. The Chinese Space Station Telescope (CSST) is expected to discover h…
