Coronal gas excitation as a tracer of supermassive black hole mass: on the mid-IR coronal [Ne v] lines

J. S. Elford, A. Prieto, A. Rodríguez-Ardila

Coronal lines (CL) may be a reliable proxy of supermassive black hole (SMBH) masses in active galactic nuclei (AGN) because the production of these high ionisation potential (IP) l…
