| Outline of Final Research Achievements |
In order to investigate the origin of the Galactic diffuse X-ray emission (GDXE), we carried out a systematic study of iron K-shell lines in the Galaxy. Using intensities of three emission lines at 6.4, 6.7 and 6.97 keV, we determined the spatial distribution and equivalent width of each line for the first time. Comparing the spatial distributions and equivalent widths with those of the cataclysmic variables and flare stars, we discussed the origin of the GDXE. We found similar diffuse X-ray emission with an intense iron K-shell line in the spiral galaxy M101. We analyzed the data of supernova remnants and extended sources in the Galaxy and obtained new results of the X-ray emission.
