| Abstract: |
We discovered an enhancement of the Ni XXVII Heα emission in Sgr D region. In the case that the Ni enhancement is part of the Galactic center X-ray emission, the [Ni]/[Fe] ratio is obtained to be 5.2±2.2. Interestingly, the Ni-rich region is located in the direction of the Sgr D SNR. In the case that the Ni-enhancement is of the SNR origin, the [Ni]/[Fe] ratio is estimated to be 66±30. The Ni-rich plasma may be the ejecta erupted from Sgr D SNR. |
