Dusty Tori of Seyfert Nuclei
Yoshiaki Taniguchi, Takashi Murayama, Hideaki Mouri
Abstract
Dusty tori around active galactic nuclei (AGNs) play an important role in the classification of Seyfert galaxies. Therefore, physical properties of dusty tori are of great interest. We briefly introduce three statistical studies investigating properties of dusty tori; 1) physical sizes of dusty tori based on water-vapor maser emission, 2) ionization condition of the inner wall of tori based on high-ionization emission lines, and 3) viewing angle toward dusty tori based on mid-infrared color.
