Description
We constrain the X-ray count rate-mass relation of 7408 RASS X-ray selected galaxy clusters at $0.05 < z < 1$. The sample is further optically confirmed based on the optical imaging from Legacy Survey DR9 and DR10, leading to a sample purity at $90\%$. We measure the weak-lensing shear profiles using the Hyper Suprime-Cam (HSC) Y3 data set, resulting in a total signal-to-noise ratio of $30.9$. Meanwhile, we measure the auto correlation of the clusters and the cross-correlation between them and the Bright Galaxy Survey (BGS) sample from the Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1). We model the measurements of the shear profiles and the correlation functions jointly to constrain the X-ray count rate-mass relation. Finally, we compare the results from small-scale weak lensing and the large-scale clustering to assess mass calibration across different scales.
