Description
The Subaru HSC survey is capable of detecting a large number of distant clusters, and a catalog of optically-selected clusters at 0.1 < z < 1.4 has been constructed. In the X-ray regime, the eROSITA survey will significantly improve both sample size and uniformity. Thus, a combination of two surveys enables us to systematically study the scaling relations and their dependence on cluster dynamical status over wide redshift and mass ranges. We search for X-ray counterparts of ~1200 optical clusters in the eFEDS field. We carry out the image and spectral analyses of high-richness clusters to determine the X-ray - BCG offset, gas temperature, and X-ray luminosity. In this paper, we present the first result of this project and plans.
