Scientific paper

Sgr A East is a young SNR located in the Galactic Center (GC) region. Since the GC region is occupied by diffuse X-ray emission (GCDX) with a strong 6.7keV line, an estimation of the GCDX is crucial to study the X-ray spectrum of Sgr A East. The flux and spectrum of the GCDX are found to be smoothly distributed around and across Sgr A East, and hence a reliable GCDX subtraction can be made. This paper presents the X-ray spectrum of Sgr A East with the XIS on board Suzaku. In addition to the previously reported Kα lines from S XV, Ar XVII, Ca XIX, and Fe XXV (all He-like atoms), we found Kα lines from S XVI, Ar XVIII, Fe XXVI (all hydrogenic atoms), and Ni XXVII (He-like), Kβ lines from S XV, Ar XVII, and Fe XXV, and a Kγ line from Fe XXV. Plasma diagnostics using these lines revealed the presence of at least a two-temperature plasma. The overall spectrum can be fitted with a two-temperature (˜1.2 keV and ˜ 6 keV) plasma in ionization equilibrium plus a power-law component.
