| 英文摘要 | We present a study of a fossil cluster, SDSS J0150–1005 (z ? 0.364), with high spatial resolution based on the imaging spectroscopic analysis of Chandra observations. The Chandra X-ray image shows a relaxed and symmetric morphology, which indicates that SDSS J0150–1005 is a well-developed galaxy cluster with no sign of a recent merger. According to the isothermal model, its global gas temperature is 5.73 ± 0.80 keV, and the virial mass is 6.23 ± 1.34 × 10~(14)M_⊙. Compared with the polytropic temperature model, the mass calculated based on the isothermal model is overestimated by 49%±11. The central gas entropy, S_(0.1r200) = 143.9 ± 18.3 keV cm~2, is significantly lower than the average value of normal galaxy clusters with similar temperatures. Our results indicate that SDSS J0150–1005 formed during an early epoch. |
