Tianqing Zhang, Sunao Sugiyama, Surhud More +13
The combination of galaxy-galaxy weak lensing and galaxy clustering is a powerful probe of the cosmological model, and exploration of how to best model and extract this information…
Mitigating Nonlinear Systematics in Weak Lensing Surveys: The Bernardeau-Nishimichi-Taruya Approach
Shiming Gu, Ludovic van Waerbeke, Francis Bernardeau +1
Weak lensing surveys, along with most other late-Universe probes, have consistently measured a lower amplitude of the matter fluctuation spectrum, denoted by the parameter , c…
Miscentering of Optical Galaxy Clusters Based on Sunyaev-Zeldovich Counterparts
Jupiter Ding, Roohi Dalal, Tomomi Sunayama +7
The "miscentering effect," i.e., the offset between a galaxy cluster's optically-defined center and the center of its gravitational potential, is a significant systematic effect on…
A Systematic Search of Distant Superclusters with the Subaru Hyper Suprime-Cam Survey
Tsung-Chi Chen, Yen-Ting Lin, Hsi-Yu Schive +13
Superclusters, encompassing environments across a wide range of overdensities, can be regarded as unique laboratories for studying galaxy evolution. Although numerous supercluster…
