Flux-ratio anomalies in cusp quasars reveal dark matter beyond CDM
Siyuan Hou, Shucheng Xiang, Yue-Lin Sming Tsai +7
Strongly lensed quasars in cusp configurations provide a uniquely sensitive probe of small-scale dark matter structure. Using the largest microlensing-free flux ratios for 17 quadr…

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…
