Key Details

Compiles data from literature to update validations and redshifts for Planck SZ galaxy clusters

Uses galaxy redshift data to identify 139 new validated clusters and 10 new strong candidates

Increases number of validated PSZ2 clusters from 1203 to 1334, with 399 updated redshifts

Updated catalog useful for combining Planck clusters with other all-sky surveys

Updated catalog of galaxy clusters from Planck Sunyaev-Zeldovich sources

This paper presents an updated catalog of galaxy clusters detected through the Sunyaev-Zeldovich (SZ) effect in Planck data. The original PSZ2 catalog contained 1653 SZ sources, with 1203 validated as galaxy clusters and 450 unvalidated candidates. By compiling additional data on cluster redshifts and member galaxies, 139 new clusters are validated, 399 have updated redshift data, and 10 new strong candidates are identified, increasing the total to 1334 validated galaxy clusters. This updated catalog will enable studies combining Planck data with other all-sky surveys.
