A Chandra view of SPT-CL J0217-5014: a massive galaxy cluster at a cosmic intersection at z=0.53
Dan Hu, Shida Fan, Zhongsheng Yuan +7
Galaxy clusters trace the densest regions of the cosmic web and are crucial laboratories for studying the thermodynamic and chemical evolution of the intracluster medium (ICM). We…
A Semi-Analytical Model for the Formation and Evolution of Radio Relics in Galaxy Clusters
Yihao Zhou, Haiguang Xu, Zhenghao Zhu +8
Radio relics are Mpc-sized synchrotron sources located in the peripheral regions of galaxy clusters. Models based on the diffuse shock acceleration (DSA) scenario have been widely…
The Merger Dynamics of the Galaxy Cluster Abell 1775: New Insights from Chandra and XMM-Newton for a Cluster Simultaneously Hosting a WAT and a NAT Radio Sources
Dan Hu, Haiguang Xu, Zhenghao Zhu +13
We present a new study of the merger dynamics of Abell~1775 by analyzing the high-quality Chandra and XMM-Newton archival data. We confirm/identify an arc-shaped edge (i.e., the he…
X-ray Intraday Variability of the TeV Blazar PKS 2155-304 with Suzaku During 2005-2014
Zhongli Zhang, Alok C. Gupta, Haritma Gaur +5
We have examined 13 pointed observations of the TeV emitting high synchrotron peak blazar PKS 2155-304, taken by the Suzaku satellite throughout its operational period. We found th…
A Study of Gas Entropy Profiles of 47 Galaxy Clusters and Groups Out to the Virial Radius
Zhenghao Zhu, Haiguang Xu, Dan Hu +6
Some observations such as those presented in Walker et al. show that the observed entropy profiles of the intra-cluster medium (ICM) deviate from the power-law prediction of adiaba…
