Abstract
We present the Suzaku results on a new candidate of a supernova remnant (SNR) in the Sagittarius C region. We detected diffuse X-rays of an elliptical shape (G359.41|$-$|0.12) and a chimney-like structure (the Chimney), both of which were fitted with a thin thermal the model of |$k_{\rm B}T$||$\sim$| 1 keV temperature. The absorption columns are same between these two structures, indicating that both are located at the same distance in the same line of sight. The narrow band image and one-dimensional profile of S xv K|$\alpha$| at 2.45 keV show that the Chimney is emanating from G359.41|$-$|0.12. Therefore, these two sources are physically connected with each other. The sum of the thermal energies of the Chimney and G359.41|$-$|0.12 is estimated to be 1.4 |$\times$| 10|$^{50}$|erg, typical for a galactic SNR. G359.41|$-$|0.12 is likely to be a new SNR candidate and the Chimney is an associated outflow.
