A General Framework for Removing Point Spread Function Additive Systematics in Cosmological Weak Lensing Analysis
Tianqing Zhang, Xiangchong Li, Roohi Dalal +10
Cosmological weak lensing measurements rely on a precise measurement of the shear two-point correlation function (2PCF) along with a deep understanding of systematics that affect i…
Weak Lensing Tomographic Redshift Distribution Inference for the Hyper Suprime-Cam Subaru Strategic Program three-year shape catalogue
Markus Michael Rau, Roohi Dalal, Tianqing Zhang +7
We present posterior sample redshift distributions for the Hyper Suprime-Cam Subaru Strategic Program Weak Lensing three-year (HSC Y3) analysis. Using the galaxies' photometry and…
Analytical Weak-lensing Shear Responses of Galaxy Properties and Galaxy Detection
Xiangchong Li, Rachel Mandelbaum
Shear estimation bias from galaxy detection and blending identification is now recognized as an issue for ongoing and future weak lensing surveys. Currently, the empirical approach…
Photometric Redshift Uncertainties in Weak Gravitational Lensing Shear Analysis: Models and Marginalization
Tianqing Zhang, Markus Michael Rau, Rachel Mandelbaum +2
Recovering credible cosmological parameter constraints in a weak lensing shear analysis requires an accurate model that can be used to marginalize over nuisance parameters describi…
Dark matter halos of luminous AGNs from galaxy-galaxy lensing with the HSC Subaru Strategic Program
Wentao Luo, John D. Silverman, Surhud More +12
We assess the dark matter halo masses of luminous AGNs over the redshift range 0.2 to 1.2 using galaxy-galaxy lensing based on imaging data from the Hyper Suprime-Cam Subaru Strate…
