Why Are Optical Coronal Lines Faint in Active Galactic Nuclei?
Forbidden collisionally excited optical atomic transitions from high-ionization-potential (IP ≥ 54.8 eV) ions, such as Ca ^4+ , Ne ^4+ , Fe ^6+ , Fe ^10+ , Fe ^13+ , Ar ^9+ , and S ^11+ , are known as optical coronal lines (CLs). The spectral energy distributions (SEDs) of active galactic nuclei (AG...
