DESI Legacy Imaging Surveys Data Release 9: Cosmological Constraints from Galaxy Clustering and Weak Lensing using the Minimal Bias Model
Haojie Xu, Hekun Li, Jun Zhang +11
We present a tentative constraint on cosmological parameters and from a joint analysis of galaxy clustering and galaxy-galaxy lensing from DESI Legacy Imaging Surveys D…

Quasi-2D Weak Lensing Cosmological Constraints Using the PDF-SYM method
Zhenjie Liu, Jun Zhang, Hekun Li +2
Cosmic shear statistics, such as the two-point correlation function (2PCF), can be evaluated with the PDF-SYM method instead of the traditional weighted-sum approach. It makes use…

Towards Optimal Reconstruction of Shear Field with PDF-Folding
Haoran Wang, Jun Zhang, Hekun Li +1
Weak lensing provides a direct way of mapping the density distribution in the universe. To reconstruct the density field from the shear catalog, an important step is to build the s…
