Outline of Final Research Achievements |
Using the Galactic plane data of Suzaku, I measured the spatial intensity fluctuation of the Galactic ridge X-ray emission (GRXE). I revealed that the combined intensity of the GRXE and cosmic X-ray background fluctuates about 3.6~8.1 % (1 sigma) over about 10 pc, except for systematic errors. This fluctuation is consistent with the prediction of the case that the GRXE is the superposition of many faint point sources. I also studied the spatial profile of the highly ionized iron line intensity ratio over a few hundred pc. It suggests that the origin of the GRXE possibly differs in the disk and bulge regions. Based on these studies, I also developed an educational material for high school students to study the Bohr model using Suzaku data.
