Catalogs of optically selected clusters and photometric luminous red galaxies from the Hyper Suprime-Cam Subaru Strategic Program final-year dataset

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 ~1200 deg². The cluster catalogs extend out to a redshift of 1.38 and contain more than 10000 clusters with richness larger than 15, where the richness is defined to be a membership probability weighted number of galaxies above the stellar masses of approximately 1010.2\, M_. The total number of probable red cluster member galaxies in these clusters is more than 6× 10⁵. Photometric redshifts of the clusters are shown to be precise with a scatter better than ~0.01 for a wide redshift range. We detect stacked weak-lensing signals of clusters out to a redshift of 1, and use them to update constraints on the mass–richness relation. Our catalog of about 6 million photometric LRGs extends to a redshift of 1.25, and has a photometric redshift scatter of better than ~0.02 for the redshift range between 0.4 and 1.0.
