VizieR Online Data Catalog: C-COSMOS & ChaMP X-ray-selected z>3 AGNs (Kalfountzou+, 2014)
Abstract
The high-redshift AGN sample used in this work has been selected from the C-COSMOS X-ray catalogue, combining the spectroscopic and photometric information available from the identification catalogue of X-ray C-COSMOS sources (Civano et al., 2011ApJ...741...91C, 2012, Cat. J/ApJS/201/30) and the ChaMP (Chandra Multi-wavelength Project) X-ray catalogue using only the 323 ChaMP obsids overlapping with Sloan Digital Sky Survey (SDSS; Richards et al., 2006, Cat. J/AJ/131/2766) DR5 imaging.
