Photometric redshifts and Galaxy Clusters for DES DR2, DESI DR9, and
  HSC-SSP PDR3 Data
  Photometric redshift (photo-z) is a fundamental parameter for
multi-wavelength photometric surveys, while galaxy clusters are important
cosmological probers and ideal objects for exploring the dense environmental
impact on galaxy evolution. We extend our previous work on estimating photo-z
and detecting galaxy clusters to the latest data releases of the Dark Energy
Spectroscopic Instrument (DESI) imaging surveys, Dark Energy Survey (DES), and
Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) imaging surveys and make
corresponding catalogs publicly available for more extensive scientific
applications. The photo-z catalogs include accurate measurements of photo-z and
stellar mass for about 320, 293, and 134 million galaxies with $r<23$, $i<24$,
and $i<25$ in DESI DR9, DES DR2, and HSC-SSP PDR3 data, respectively. The
photo-z accuracy is about 0.017, 0.024, and 0.029 and the general redshift
coverage is $z<1$, $z<1.2$, and $z<1.6$, respectively for those three surveys.
The uncertainties of the logarithmic stellar mass that is inferred from stellar
population synthesis fitting is about 0.2 dex. With the above photo-z catalogs,
galaxy clusters are detected using a fast cluster-finding algorithm. A total of
532,810, 86,963, and 36,566 galaxy clusters with the number of members larger
than 10 are discovered for DESI, DES, and HSC-SSP, respectively. Their photo-z
accuracy is at the level of 0.01. The total mass of our clusters are also
estimated by using the calibration relations between the optical richness and
the mass measurement from X-ray and radio observations. The photo-z and cluster
catalogs are available at ScienceDB
