Abstract
Spectroscopy in the mid-infrared spectral range provides a number of unique diagnostics of active galactic nuclei which can now be used thanks to ISO’s sensitivity and full wavelength coverage. Mid-infrared aromatic emission features are absent close to the AGN but can be strong on larger host galaxy scales, in particular if there is intense circumnuclear star formation. The rich.ne structure and coronal line spectrum can be used to reconstruct the otherwise unobservable extreme ultraviolet emission of the AGN. We find evidence for ‘bigblue bump’ emission from the accretion disk but also for neutral absorbers located inside the narrow line region. The ability of mid-infrared emission to penetrate dust allows to probe the structure of dusty narrow line regions, and to search for the obscured broad line region in Seyfert 2 galaxies.
