Title:  Infrared 3-4 micron spectroscopic investigations of 
       nuclear starbursts in Seyfert 1 and 2 galaxies   
Authors: Masatoshi Imanishi 
Topic: 9 (or 6 if more appropriate) 
Session: oral 
Abstract: We performed infrared 3-4 micron spectroscopy of 
>50 Seyfert galaxies. The nuclear starburst luminosities in dusty 
tori are quantitatively estimated from the 3.3 micron 
PAH emission luminosities, a good starburst indicator. We 
find that nuclear starstarburst luminosity positively correlates 
with AGN power, suggesting their physical connections.

Title:  Luminous buried AGNs in the local universe 
Authors: Masatoshi Imanishi 
Topic: 6 
Session: poster 
Abstract: We performed systematic infrared 3-4 micron 
spectroscopic searches for AGNs deeply buried in dust in all 
directions. Unlike AGNs surrounded by torus-shaped dust, 
buried AGNs are elusive, but are predicted to be 
abundant. We found buried AGN signatures in many luminous 
infrared galaxies (Imanishi et al. 2006 ApJ 637 114).
