Extended coronal emission lines in active galactic nuclei
VLT and NTT spectra are used to examine the nuclear and extended coronal line emission in a sample of well-known Seyfert 1 and 2 galaxies. The excellent spatial...
Far IR (90 microns) ISO Maps of four Seyfert galaxies are presented. We find that the Far Infrared emission is extended in all cases out to radii comparable to...
The authors have analyzed far-IR (IRAS) data for a sample of optically selected Seyfert galaxies. The far-infrared emission is uncorrelated, or at best weakly...
Preliminary results of a program aimed at investigating the presence of H II regions around Seyfert nuclei are presented. Extended zones of ionized gas have...
Extended line emission in AGN: Looking at the central engine
The regions of high excitation gas detected around various Active Galactic Nuclei (AGN) are examined. The radiation emitted by the nucleus may be responsible...
Extended line emission in AGN: looking at the central engine.
Regions of high excitation gas were detected around various active galactic nuclei. Their shape resembles a cone whose axis is oriented close to the radio axis...
