VizieR Online Data Catalog: The Chandra X-ray Galaxy Catalog (CGC) (Kim+, 2023)
Abstract
The Chandra Source Catalog version 2 (CSC2; IX/57), released in 2019, makes use of the first 15yr of Chandra observations (1999-2014), coadded in overlapping regions of the sky to achieve the best sensitivity. The CSC2 includes 317167 unique X-ray sources with accurate positions and high-quality photometric, spectral, and temporal properties.
We crossmatched 117358 high-quality X-ray sources selected from CSC2 with optical, IR, and UV catalogs to identify galaxies and obtain multiwavelength data using the all-sky surveys SDSS DR16 (V/154), PanSTARRS DR2, DESI Legacy DR8 (VII/292), AllWISE (II/328), 2MASS (II/246) and GALEX (II/335).
