Coronal Lines in Seyfert Galaxies

Forbidden lines of high ionisation stages (e.g. [FeIV], [FeX],[ FeXI], [FeXIV]) are an important tool to study the stratification (ionisation potential - line width) in line-emitting regions of AGN. They also provide an opportunity to study X-ray absorbing plasma at high spectroscopic resolution.
