Query: Clusters of galaxies up to z=1.5 identified from photometric data of the
  Dark Energy Survey and unWISE   Using photometric data from the Dark Energy Survey and the Wide-field
Infrared Survey Explorer, we estimate photometric redshifts for 105 million
galaxies using the nearest-neighbour algorithm. From such a large database,
151,244 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 76,826 clusters are newly identified
and 30,477 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% SZ clusters in the sky region have counterparts in
our catalogue. We find multiple optical clusters in the line of sight towards
about 15% of SZ clusters.
