An evaluation of source-blending impact on the calibration of SKA EoR experiments

Chenxi Shan, Haiguang Xu, Yongkai Zhu +8

Twenty-one-centimetre signals from the Epoch of Reionization (EoR) are expected to be detected in the low-frequency radio window by the next-generation interferometers, particularl…

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…

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…

Murchison Widefield Array detection of steep-spectrum, diffuse, non-thermal radio emission within Abell 1127

Stefan W. Duchesne, Melanie Johnston-Hollitt, Zhenghao Zhu +2

Diffuse, non-thermal emission in galaxy clusters is increasingly being detected in low-frequency radio surveys and images. We present a new diffuse, steep-spectrum, non-thermal rad…

A Monte Carlo Implementation of Galactic Free-Free Emission for the EoR Foreground Models

Xiaoli Lian, Haiguang Xu, Dongchao Zheng +2

The overwhelming foreground causes severe contamination on the detection of 21-cm signal during the Epoch of Reionization (EoR). Among various foreground components, the Galactic f…
