A Chandra study of the massive, distant galaxy cluster SDSS J0150–1005
《Research in Astronomy and Astrophysics》2013年第10期1155-1162,共8页Zhen-Zhen Qin Hai-Guang Xu Jing-Ying Wang Jun-Hua Gu 
Supported by the National Natural Science Foundation of China(Grant Nos. 10878001, 10973010 and 11125313);the National Basic Research Program of China (973 Program; Grant Nos. 2009CB824900 and 2009CB824904);the Shanghai Science and Technology Commission (Program of Shanghai Subject Chief Scientist; Grant Nos. 12XD1406200 and 11DZ2260700)
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...

Biases in hydrostatic mass profiles introduced by hot gas substructures:Chandra study of four galaxy clusters
《Research in Astronomy and Astrophysics》2010年第10期1005-1012,共8页Li-Yi Gu Yu Wang Jun-Hua Gu Jing-Ying Wang Zhen-Zhen Qin Meng-Yu Yao Jian-Long Yang Hai-Guang Xu 
supported by National Natural Science Foundation of China(Grant Nos.10673008,10878001and10973010);the Ministry of Science and Technology of China(Grant No.2009CB824900/2009CB24904);the Ministry of Education of China(the NCET Program)
By analyzing the azimuthal variations of total gravitating mass profiles in the central 300 h^-1 71 kpc regions of four galaxy clusters with Chandra data, we find that the azimuthally-averaged mass profiles may have b...

Spatial distribution of metal emissions in supernova remnant 3C 397 viewed with Chandra and XMM
《Science China(Physics,Mechanics & Astronomy)》2010年第S1期267-270,共4页JIANG Bing & CHEN Yang Department of Astronomy,Nanjing University,Nanjing 210093,China 
support by the National Natural Science Foundation of China (Grant Nos. 10725312 and 10673003);the National Basic Research Program of China (Grant No. 2009CB824800)
We present X-ray equivalent width imaging of 3C 397 for Mg Heα,Si Heα,S Heα,and Fe Kα complex lines with Chandra and XMM-Newton observations.The images revealed that the heavier the element is,the smaller the exte...

Chandra archival study of (U)LIRGs with a double nucleus:binary AGNs?
《Research in Astronomy and Astrophysics》2010年第4期309-328,共20页Jing-Bo Wang Yu Gao 
supported by the National Natural Science Foundation of China(Distinguished Young Scholars,Grant Nos.10425313,10833006 and 10621303);Chinese Academy of Sciences’Hundred Talent Program;973 project of the Ministry of Science and Technology of China(GrantNo.2007CB815406)
We present our initial results from a study of 14 （U）LIRGs with a doublenucleus （z 〈0.15） and an AGN signature in the Chandra archive.The goals of our study are to search for more possible cases of binary AGNs an...
