AbstractWe report results of the Suzaku observation toward the Sagittarius (Sgr) D region. Diffuse X-ray emission was clearly detected from inside the shell-type supernova remnant, the Sgr D SNR and is named G 1.02-0.18. A hint of an iron line is seen in the spectrum, suggesting that G 1.02-0.18 is a thin thermal plasma with the temperature of kT 2 keV . Its physical parameters (e.g. the plasma density, mass, thermal energy) suggest that G 1.02-0.18 is an SNR candidate and is possibly associated with the Sgr D SNR. We also analyzed data from another bright X-ray source SAX J1748.2-2808, which was in the field of view of Suzaku. A coherent pulsation with a period of 593s and emission lines from neutral and highly ionized irons were discovered. These results indicate that SAX J1748.2-2808 is likely to be an intermediate polar.
