Searching for Compact Obscured Nuclei in Compton-thick Active Galactic Nuclei

Compact obscured nuclei (CONs) are heavily obscured infrared cores that have been found in local (ultra-)luminous infrared galaxies. They show bright emission from vibrationally excited rotational transitions of HCN, known as HCN-vib, and are thought to harbor Compton-thick (CT, N _H ≥ 10 ^24 cm ^−2...
