SEARCH FOR NEW SNR CANDIDATES IN THE GALACTIC CEN- TER REGION WITH CHANDRA

Abstract

Abstract We report the diffuse X-ray features which are possible SNR candidates near the Galactic Center (GC) observed with Chandra. G0.570−0.018 has a extremely small (20 diameter) shelllike morphology. The X-ray spectrum exhibits a strong Fe-K line emission and is well fitted by NEI model with a temperature of about 6 keV. These features suggest that G0.570−0.018 is a quite young (t ∼ 100 year) SNR. Diffuse hard X-ray were also detected from G359.92−0.09. The X-ray spectrum exhibits strong Fe-K line emission. The X-ray excess coincides with the shell-type feature observed with radio continuum (e.g
