  Title: EVOLUTION OF ULTRALUMINOUS IRAS GALAXIES                                        


Abstract:
 Ultra luminous FIR galaxies (hereafter ULFIRGs) have high luminoity of L>1E12Lo,
 which is comparable to that of QSO. Images of the ULFIRGs show that nearly all are
 strongly interacting merger system. Sanders et al. (1988) proposed an evolutionary
 connection between ULFIRGs and QSO. In their model, ULFIRG has a buried nucleus
 under a circumnuclear dust. The activity of nucleus will dominate, decaying
 starburst activity, then it becomes optically selected QSO. We would like to
 investigate the transition between ULFIRG and QSO. In recent, galaxy interaction can
 be well demonstrated with a computer simulation, with which the age can be
 estimated, comparing the simulation with observations. We select two ULFIRGs with diffrent stage of interacting merger.
