Multicolor Optical Imaging of Infrared-Warm Seyfert Galaxies. V. Morphologies and Interactions: Challenging the Orientation Model

摘要: This paper is the last in a series investigating optical properties of sample mid-IR warm Seyfert galaxies and control cold galaxies. In present I parametrize morphologies interaction host combine these with major conclusions my previous papers. My results confirm that nuclear activity linked to galactic interactions. suggest an alternative view simple orientation-obscuration model postulated for types 1 2 takes into account time evolution their environmental morphological properties. Within this view, distinction between not one orientation; latter might instead represent earlier evolutionary stage, intermediate (starburst-dominated) (AGN-dominated)
