| Research Abstract |
Using the Suzaku data observed in the Galactic center, Galactic plane, and Galactic bulge regions, I studied properties of Fe-K emission lines of the Galactic diffuse X-ray emission. The ratios of 6. 97keV/6. 7 keV in the Galactic center and the Galactic bulge regions are systematically larger than that of the Galactic plane. The observed Fe emission line cannot be reproduced by a spectral model for active star binaries and white dwarf binaries. We also studied newly discovered X-ray sources and supernova remnants.
