摘要:

我们提出了朱雀的结果在人马座C区的超新星遗迹(SNR)的新候选人。我们探测到椭圆形(G359.41-0.12)和烟囱状结构(烟囱)的漫射X射线,这两者都符合kBT ~1 keV温度的薄热模型。这两个结构之间的吸收柱相同,表明两者位于同一视线中的相同距离处。在2.45 keV的S XV Ka的窄带图像和一维轮廓表明,烟囱是从G359.41-0.12发出。因此,这两个源彼此物理连接。烟囱和G359.41-0.12的热能之和估计为1.4x10^50 erg,这是典型的银河SNR。G359.41-0.12可能是一个新的SNR候选,烟囱是一个相关的流出。

英文摘要:

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 kBT ~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 Kalpha 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 1.4x10^50 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.
