Despite this, the X-ray emissions from CT-AGNs are believed to be a substantial contributor to the cosmic X-ray background (CXB). According to synthesis models of AGNs, CT-AGNs are expected to make up a significant fraction of the AGN population, likely around 30% or more. However, only $\\sim$11% of AGNs have been identified as CT-AGNs in the Chandra Deep Field-South (CDFS).
