[11.15] Slitless Spectroscopy of 10 Seyfert Galaxies

A sample of ten Seyfert galaxies (9 Seyfert 2s, and 1 Seyfert 1) are examined using the Space Telescope Imaging Spectrograph, the Wide Field Planetary Camera and the Faint Object Camera on board the Hubble Space Telescope. The kinematics of the ionized gas condensations within the narrow-line region (NLR) are mapped out to ~ 1 kpc from the nucleus. These kinematic results are then modeled onto a biconical distribution, consistent with observed NLR morphologies (i.e., ionization cones). Best-fit values are obtained for aspect parameters of this configuration relative to the host galaxy.

Presented here are the NLR radial velocity maps, best-fit values of the biconical models and implications of these models for the entire sample.
