COMPARING IMAGES OF SEYFERT GALAXIES IN MULTIPLE BANDS

Galaxies with Active Galactic Nuclei (AGN) are expected to host a considerable amount of gas and dust that emit strongly in the mid-infrared (MIR) and can be related to structures seen in other bands. This dust can either be associated with the AGN phenomenon itself or concentrated in star formation regions on a variety of scales. We quantify and examine the spatial cross-correlation of the extended structure (> 100pc from nucleus) in various emission line images, X-ray images, and MIR images of a sample of fi ve Seyfert galaxies. Previous studies have determined that each object in the sample shows thermal emission from warm dust that is primarily heated by either the AGN central engine or by star formation. We cannot define any trends with such a small sample, but we find that both varieties have significant correlation between their Pa® and MIR images, and the AGN-dominated galaxies usually have significnt correlation between their OIII images and MIR images. We find only one case of significant correlation between the X-ray and MIR images, in an object dominated by star formation.
