A Semi-Analytical Model for the Formation and Evolution of Radio Relics in Galaxy Clusters

Autor: Yihao Zhou, Haiguang Xu, Zhenghao Zhu, Yuanyuan Zhao, Shida Fan, Chenxi Shan, Yongkai Zhu, Lei Hao, Li Ji, Zhongli Zhang, Xianzhong Zheng

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 accepted to explain the formation of radio relics. However, a critical

The Merger Dynamics of the Galaxy Cluster A1775: New Insights from Chandra and XMM-Newton for a Cluster Simultaneously Hosting a Wide-angle Tail and a Narrow-angle Tail Radio Source

Autor: Chengze Liu, Zhenghao Zhu, Chenxi Shan, Hoongwah Siew, Xi Kang, Jiang Chang, Qinghua Tan, Melanie Johnston-Hollitt, Shida Fan, Yongkai Zhu, Zhongli Zhang, Xiang-Ping Wu, Dan Hu, Haiguang Xu, Liyi Gu, Yuanyuan Zhao

Publikováno v: The Astrophysical Journal. 913:8

We present a new study of the merger dynamics of A1775 by analyzing the high-quality Chandra and XMM-Newton archival data. We confirm/identify an arc-shaped edge (i.e., the head) at ∼48 kpc west of the X-ray peak, a split cold gas tail that extends

A Study of Gas Entropy Profiles of 47 Galaxy Clusters and Groups out to the Virial Radius

Autor: Yongkai Zhu, Liyi Gu, Shida Fan, Zhenghao Zhu, Xiang-Ping Wu, Yuanyuan Zhao, Chenxi Shan, Haiguang Xu, Dan Hu

Publikováno v: The Astrophysical Journal. 908:17

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 adiabatic simulations. This implies that non-gravitational processes, which

Separating the EoR Signal with a Convolutional Denoising Autoencoder: A Deep-learning-based Method

Autor: Zhixian Ma, Ruimin Zhu, Haiguang Xu, Junhua Gu, Xiang-Ping Wu, Jie Zhu, Weitian Li, Zhenghao Zhu, Dan Hu, Chenxi Shan

When applying the foreground removal methods to uncover the faint cosmological signal from the epoch of reionization (EoR), the foreground spectra are assumed to be smooth. However, this assumption can be seriously violated in practice since the unre

A Study of the Merger History of the Galaxy Group HCG 62 Based on X-Ray Observations and Smoothed Particle Hydrodynamic Simulations

Autor: Liyi Gu, Xiang-Ping Wu, Xi Kang, Weitian Li, Zhongli Zhang, Dan Hu, Haiguang Xu, Chengze Liu, Zhenghao Zhu, Chenxi Shan, Qian Zheng, Zhixian Ma

Publikováno v: The Astrophysical Journal

We chose the bright compact group HCG 62, which has been found to exhibit both excess X-ray emission and high Fe abundance to the southwest of its core, as an example to study the impact of mergers on chemical enrichment in the intragroup medium. We

Autor: Chengze Liu, Weitian Li, Jie Zhu, Zhixian Ma, Haiguang Xu, Liyi Gu, Xiang-Ping Wu, Jinjin Li, Chenxi Shan, Dan Hu, Zhenghao Zhu

We present a morphological classification of 14,245 radio active galactic nuclei (AGNs) into six types, i.e., typical Fanaroff--Riley Class I / II (FRI/II), FRI/II-like bent-tailed, X-shaped radio galaxy, and ringlike radio galaxy, by designing a con
