Abstract

We construct samples of optically-selected clusters and photometric luminous red galaxies (LRGs) from the Hyper Suprime-Cam Subaru Strategic Program final year dataset covering ~deg. The cluster catalogs extend out to the redshift of and contain more than 10000 clusters with richness larger than , where the richness is defined to be a membership probability weighted number of galaxies above the stellar masses of approximately . The total number of probable red cluster member galaxies in these clusters are more than . Photometric redshifts of the clusters are shown to be precise with the scatter better than for a wide redshift range. We detect stacked weak lensing signals of clusters out to the redshift of , and use them to update constraints on the mass-richness relation. Our catalog of about 6 million photometric LRGs extend out to the redshift of , and have the scatter of the photometric redshift better than for the redshift range between and .
