AbstractBy using a large, highly obscured ( N-H > 10(23) cm(-2)) active galactic nucleus (AGN) sample (294 sources at z similar to 0-5) selected from detailed X-ray spectral analyses in the deepest Chandra.surveys, we explore distributions of these X-ray sources in various optical/infrared/X-ray color-color diagrams and their host-galaxy properties, aiming at characterizing the nuclear obscuration environment and the triggering mechanism of highly obscured AGNs. We find that the refined Infrared Array Camera (IRAC) color-color diagram fails to identify the majority of X-ray-selected, highly obscured AGNs, even for the most luminous sources with log L-X(erg s(-1)) > 44. Over 80% of our sources will not be selected as heavily obscured candidates using the flux ratio of f(24 mu m)/f(R) > 1000 and R - K > 4.5 criteria, implying complex origins and conditions for the obscuring materials that are responsible for the heavy X-ray obscuration. The average star formation rate (SFR) of highly obscured AGNs is similar to that of stellar mass-(M*-) and z-controlled normal galaxies, while a lack of quiescent hosts is observed for the former. Partial correlation analyses imply that highly obscured AGN activity (traced by L-X) appears to be more fundamentally related to M*, and no dependence of N-H on either M* or SFR is detected. Morphology analyses reveal that 61% of our sources have a significant disk component, while only similar to 27% of them exhibit irregular morphological signatures. These findings together point toward a scenario where secular processes (e.g., galacticdisk instabilities), instead of mergers, are most probable to be the leading mechanism that triggers accretion activities of X-ray-selected, highly obscured AGNs.
