Completing the census of active galactic nuclei (AGN) activity is the key to study the build-up of supermassive black holes (SMBHs) and understand their relations with the host galaxy properties. Nevertheless, many AGNs are obscured by dust and gas, making the identification of such systems a challenging task even today. In this talk, I will summarize our current understanding of the AGN obscuring structures and how we can use this knowledge to pick out obscured AGNs in the JWST era. For the former, I will describe a relatively simple framework that intergrates the studies of the IR spectral energy distributions (SEDs), time variability and spatially-resolved observations covering large ranges of AGN luminosity and redshift. For the latter, I will talk about what have been learned from selecting AGNs in the GOODS-S/HUDF with archival X-ray to the radio-band data and introduce our JWST NIRCam and MIRI surveys of the same field. |
