5. Abstract

We propose to analyze archival OIIILambda5007Angstrom\ images of 14 Seyfert
galaxies. These data will be used to complement a snapshot survey proposal to obtain
narrow band OIIILambda5007Angstrom\ images for a well defined sample of 190 Seyfert
galaxies (52 Seyfert 1s and 138 Seyfert 2s), selected from a mostly isotropic
property, the 60Mum luminosity. These data will be used: 1) to study the frequency
of conically shaped Narrow Line Regions (NLR) in Seyfert galaxies, which are usually
unresolved from ground- based observations and to compare the size and shape of the
NLR of Seyfert 1s and Seyfert 2s; 2) to measure the orientation of the accretion
disk relative to the host galaxy disk, so as to establish whether indeed the
accretion disk axis avoids close alignment with the host galaxy disk axis as
indicated in early studies and; 3) to compare the spatial relation between radio and
NLR emission, using OIII images and radio maps of comparable resolution. We aim to
provide a critical test of the applicability and limitations of the Unified Schemes
that currently are the framework for understanding Seyfert galaxies and their
luminous counterparts, AGN.
