Accurate field-level weak lensing inference for precision cosmology
Alan Junzhe Zhou, Xiangchong Li, Scott Dodelson +1
We present , a catalog-to-cosmology pipeline for general flat-sky field-level inference, which provides access to cosmological information beyond the two-point stati…
Three-Dimensional Reconstruction of Weak-Lensing Mass Maps with a Sparsity Prior. II. Weighing Triaxial Cluster Halos
Shouzhuo Yang, Xiangchong Li, Naoki Yoshida
Continuing work presented in Li et al. (2021), we performed a series of tests to our high-resolution three-dimensional mass map reconstruction algorithm \splinv{}. We test the mass…
Optical Cluster Cosmology with SDSS redMaPPer clusters and HSC-Y3 lensing measurements
Tomomi Sunayama, Hironao Miyatake, Sunao Sugiyama +9
We present cosmology results obtained from a blind joint analysis of the abundance, projected clustering, and weak lensing of galaxy clusters measured from the Sloan Digital Sky Su…
A Differentiable Perturbation-based Weak Lensing Shear Estimator
Xiangchong Li, Rachel Mandelbaum, Mike Jarvis +3
Upcoming imaging surveys will use weak gravitational lensing to study the large-scale structure of the Universe, demanding sub-percent accuracy for precise cosmic shear measurement…
