cds-question@unistra.fractive-galactic-nucleix-ray-sourcesredshiftedinfrared-photometryvisible-astronomyphotometryWe perform X-ray spectral analyses to derive the characteristics (e.g., column density, X-ray luminosity) of ~10200 active galactic nuclei (AGNs) in the XMM-Spitzer Extragalactic Representative Volume Survey, which was designed to investigate the growth of supermassive black holes across a wide dynamic range of cosmic environments. Using physical torus models (e.g., Borus02) and a Bayesian approach, we uncover 22 representative Compton-thick (CT; N_H_>1.5x10^24^cm^-2^) AGN candidates with good signal-to-noise ratios as well as a large sample of 136 heavily obscured AGNs. We also find an increasing CT fraction (f_CT_) from low (z<0.75) to high (z>0.75) redshift. Our CT candidates tend to show hard X-ray spectral shapes and dust extinction in their spectral energy distribution fits, which may shed light on the connection between AGN obscuration and host-galaxy evolution.2023ApJ...951...27Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/951/27CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/371 : The Dark Energy Survey (DES): Data Release 2 (Abbott+, 2021)IX/69 : XMM-Newton Serendipitous Source Catalogue 4XMM-DR13 (Webb+, 2023)J/A+A/564/A125 : AGN Torus model comparison of AGN in CDFS (Buchner+, 2014)J/ApJ/802/89 : Luminosity function of X-ray-selected AGNs (Buchner+, 2015)J/MNRAS/478/2132 : XMM-LSS field.
