Mapping Dark Matter in Merging Clusters with Weak Lensing for CSST: Morphology and Filament Recovery
Xinyue Chen, Ran Li, Qiao Wang +6
Weak gravitational lensing offers a direct probe of the projected dark matter distribution in cluster-scale structures and the surrounding cosmic web. We investigate the capability…

MIU2Net: weak-lensing mass inversion using deep learning with nested U-structures
Han W. G., An Zhao, Xinyue Chen +5
One of the primary goals of next-generation gravitational lensing surveys is to measure the large-scale distribution of dark matter, which requires accurate mass inversion to conve…

A Comparative Study of Halo Mass Estimates from Group Catalogs and Lensing Signals
Xinyue Chen, Weiwei Xu, Ran Li +3
We compare halo mass estimates from three galaxy group catalogs (redMaPPer, Yang21, and Zou21) with those derived from gravitational lensing measurements. Each catalog employs dist…
