STUDY OF ACCRETION DISC ILLUMINATED BY STRONG RADIATION --- FE K LINE PROFILE OF IRAS18325-5926
ABSTRACT
The broad Fe K line profile found in AGN spectra is the most important result to investigate accretions discs around massive blackholes. Among many AGN's with such line feature, the line width and equivalent width is largest for IRAS18325-5926. In the spectra observed in the PV phase, the high energy side of the line profile extends up to 7 keV, which suggests highly ionized ions or larger inclination angle. It is worth observing IRAS18325 as long as 200 ksec to conclude it with enough statistics. It has been also reported that the broad line feature changes during the total flux change. We propose to observe IRAS18325 for 200 ksec to monitor the flux change as well as the change of line profile to examine the disc size, structure and its physical status.
