  Title: X-RAY STUDY OF THE ENERGY SOURCE IN ULTRA LUMINOUS INFRARED GALAXIES - A POWERFUL STARBURST OR A HIDDEN QSO? -


Abstract:
 We propose to observe two ultraluminous infrared galaxies and to examine energy
 source in them using ASCA. Although they have huge far-infrared luminosity around
 10**12Lsolar, their optical and near infrared emission lines indicate only starburst
 activity and there is no clear evidence for AGN. If IR luminosity comes from only
 starburst activity, it is the first example of the most powerful starburst, about
 100 times more active than a prototype starburst galaxy M82. While if a hidden AGN
 is present, it is the first evidence of AGN through all wave length and it may be type2 QSO.
