Chandra Studies of the X-ray gas properties of fossil systems
《Research in Astronomy and Astrophysics》2016年第3期129-138,共10页Zhen-Zhen Qin 
supported by the Research Fund for the Doctoral Program of the Southwest University of Science and Technology (No. 14zx7102)
We study ten galaxy groups and clusters suggested in the literature to be ＂fossil systems（FSs）＂based on Chandra observations. According to the M（500）- T and LX- T relations, the gas properties of FSs are not phy...
