1. Suzaku perspective on the Galactic Center
The “40-keV Plasma” vs “10-keV Plasma”
What is the Origin of the 6.7 keV-line Plasma ?
Are the Galactic Center and Ridge emissions Same Origin ?
Big bang of Sgr A* or Multi-SNe or ?

9. Key Questions on the iron line
ASCA Mapping with thw3-iron Lines
Key Questions on the iron line
Which line is cｌumpy ?
Only 6.4 keV line (XRN) ?
How about 6.7 and 6.9 keV lines ?
Are these intensities and
the line ratio uniform ?
Any non-thermal structure ?
