Description
The coronal line region in AGN is an intermediate zone between the
broad- and the narrow-line regions where lines with ionization
potentials, IP >50 eV, are produced. Because these IP are not easily
reachable in stars, coronal lines become unique tracers of the AGN
activity. The coronal line region has so far remained unresolved as its
typical size is of a few tens of pc. However, these sizes are now
accessible to the diffraction limit of an 8 m telescope.
