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...
Extended Point-spread Functions for Deep Astronomical Imaging Surveys
The low surface brightness (LSB) universe is one of the last frontiers in observational astronomy. However, uncovering the information contained in ultra-deep...
Extended PSF for deep imaging astronomical surveys
