Clusters of galaxies from DES*unWISE data

From such a large data base, 151244 clusters of galaxies are identified in the redshift range of 0.1 < z <= 1.5 based on the overdensity of the total stellar mass of galaxies within a given photometric redshift slice, among which 76826 clusters are newly identified and 30477 clusters have a redshift z > 1.

We cross-match these clusters with those in the catalogues identified from the X-ray surveys and the Sunyaev-Zel'dovich (SZ) effect by the Planck, South Pole Telescope and Atacama Cosmology Telescope surveys, and get the redshifts for 45 X-ray clusters and 56 SZ clusters. More than 95 per cent SZ clusters in the sky region have counterparts in our catalogue. We find multiple optical clusters in the line of sight towards about 15 per cent of SZ clusters.
