VizieR Online Data Catalog: Type 1 vs 2 X-ray-selected COSMOS AGNs & environment (Zou+, 2019)
Abstract
Our sample is drawn from X-ray-detected sources in the COSMOS-Legacy Survey (Civano+ 2016, J/ApJ/819/62). The high angular resolution of Chandra (~0.5") in the COSMOS-Legacy Survey enables reliable cross-matching between the X-ray catalog and IR-to-ultraviolet (UV) catalogs (Marchesi+ 2016, J/ApJ/817/34).
In total, 2463 sources are left after removing the masked sources (see Section 2). We adopt the redshifts in Marchesi+ (2016, J/ApJ/817/34), and 1434 sources have reliable spectroscopic redshift measurements. Throughout this paper, we adopt a flat ΛCDM cosmology with H0=70km/s/Mpc, ΩΛ=0.73, and ΩM=0.27. (1 data file).- Publication:
