The origin of gas in the Extended Narrow Line Region of nearby Seyfert galaxies.I. NGC 7212
V. Cracco, S. Ciroi, F. Di Mille +6
The Extended Narrow Line Region (ENLR) of Active Galactic Nuclei (AGN) is a region of highly ionized gas with a size of few up to 15-20 kpc. When it shows a conical or bi-conical s…

Emission line profiles and X-ray observations of Broad and Narrow Line Seyfert 1 Galaxies
G. La Mura, S. Ciroi, V. Cracco +3
Narrow Line Seyfert 1 galaxies represent a distinct category in the larger family of Type 1 Active Galactic Nuclei. The occurrence of emission line profiles not broader than 2000 k…
