Lambda as a Probe of Lensing Consistency
Yuan Shi, Li Cui, Carlo Giocoli
We introduce a framework to identify the radial transition in mass reconstruction reliability between strong and weak gravitational lensing in galaxy clusters. In weak lensing reco…

AKRA 3.0: A matrix-free Inversion Framework for Weak Lensing Mass Mapping and Its Application to DES Y3 Data
Yuan Shi, Pengjie Zhang, Li Cui +2
Weak gravitational lensing mass mapping offers a direct probe of the matter distribution. Accurate reconstruction of mass maps from masked shear catalogs remains challenging due to…
