The Shear-to-Cosmology Paradigm I. Hybrid Field-Level and Simulation-Based Framework for Weak Lensing Surveys
Jiacheng Ding, Chen Su, Ji Yao +2
Precise cosmological inference from next-generation weak lensing surveys requires extracting non-Gaussian information beyond standard two-point statistics. We present a hybrid mach…

Cosmological Constraints with Void Lensing I: the Simulation-Based Inference Framework
Chen Su, Huanyuan Shan, Cheng Zhao +2
We present a Simulation-Based Inference (SBI) framework for cosmological parameter estimation via void lensing analysis. Despite the absence of an analytical model of void lensing,…
