A Chandra Study of Temperature Substructures in Intermediate-Redshift Galaxy Clusters
Liyi Gu, Haiguang Xu, Junhua Gu +6
By analyzing the gas temperature maps created from the Chandra archive data, we reveal the prevailing existence of temperature substructures on ~100 kpc scales in the central regio…
Probing the Mass Distributions in NGC 1407 and Its Associated Group with the X-ray Imaging Spectroscopic and Optical Photometric and Line-strength Indices Data
Zhongli Zhang, Haiguang Xu, Yu Wang +3
We present a study of the mass distributions in the bright E0 galaxy NGC 1407 and its associated group by analyzing the high quality Chandra and ROSAT X-ray spectroscopic data. In…
Chandra Observation of the Cluster of Galaxies MS 0839.9+2938 at z=0.194: the Central Excess Iron and SN Ia Enrichment
Yu Wang, Haiguang Xu, Zhongli Zhang +4
We present the Chandra study of the intermediately distant cluster of galaxies MS 0839.9+2938. By performing both the projected and deprojected spectral analyses, we find that the…
Chandra Study of X-Ray Point Sources in the Early-Type Galaxy NGC 4552 (M89)
Yueheng Xu, Haiguang Xu, Zhongli Zhang +3
We present a Chandra ACIS study of the early-type galaxy NGC 4552. We detect 47 X-ray point sources, most of which are likely LMXBs, within 4 R_e. The brightest X-ray source coinci…
