Presenter: I-Non Chiu (National Cheng Kung University)

I will present cosmological constraints using the abundance of weak-lensing shear-selected galaxy clusters selected in the Hyper Suprime-Cam (HSC) Subaru Strategic Program. The clusters are selected on the mass maps constructed using the latest three-year (Y3) weak-lensing data with an area of ≈ 500 deg2, resulting in a sample size of 129 clusters with a high signal-to-noise ratio
