Constraining Neutrino Mass with the Void Weak Lensing Effect
Wenshuo Xu, Cheng Zhao, Chen Su +2
Cosmic voids, the underdense regions of the Large Scale Structure (LSS), provide cosmological information highly complementary to that obtained from overdense regions. In this work…
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,…
CURLING - I. The Influence of Point-like Image Approximation on the Outcomes of Cluster Strong Lens Modeling
Yushan Xie, Huanyuan Shan, Nan Li +11
Cluster-scale strong lensing is a powerful tool for exploring the properties of dark matter and constraining cosmological models. However, due to the complex parameter space, pixel…
Void Lensing in Cubic Galileon Gravity
Chen Su, Huanyuan Shan, Jiajun Zhang +6
Weak lensing studies via cosmic voids are a promising probe of Modified Gravity (MG). Excess surface mass density (ESD) is widely used as a lensing statistic in weak lensing resear…
