The Quiescent Sloshing Core of Abell 496 with XRISM
Angie Veronica, Thomas H. Reiprich, Naomi Ota +9
Gas motions provide insight into the dynamical history and physical processes within galaxy clusters. We investigate the kinematics of the ICM in the core of A496, a nearby, X-ray…
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…
Solving the cooling flow problem with combined jet-wind AGN feedback
Aoyun He, Feng Yuan, Suoqing Ji +6
Active galactic nucleus (AGN) feedback is widely viewed as the most promising solution to the long-standing cooling flow problem in galaxy clusters, yet previous models prescribe j…
MeerKAT discovery of GHz radio emission extending from Abell 3017 toward Abell 3016
Dan Hu, Norbert Werner, Haiguang Xu +18
Context: The clusters Abell 3017 and Abell 3016 are located within a large-scale filament. A prominent X-ray bridge has been detected connecting the two clusters and a potential ga…
The warm-hot intergalactic medium in inter-cluster filaments -- A forecast for HUBS observations based on eRASS1 superclusters
Yuanyuan Zhao, Haiguang Xu, Ang Liu +8
Cosmological simulations indicate that nearly half of the baryons in the nearby Universe are in the warm-hot intergalactic medium (WHIM) phase, and about a half them reside in cosm…
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…
Constraints on Hairy Kerr black hole with quasi-periodic oscillations
Cheng Liu, Hoongwah Siew, Tao Zhu +3
The Hairy Kerr black hole is a novel black hole solution that depicts a rotating space-time encompassed by an axisymmetric fluid. It has significant observational importance and is…
Scientific Objectives of the Hot Universe Baryon Surveyor (HUBS) Mission
Joel Bregman, Renyue Cen, Yang Chen +51
The Hot Universe Baryon Surveyor (HUBS) is a proposed space-based X-ray telescope for detecting X-ray emissions from the hot gas content in our universe. With its unprecedented spa…
Constraints on the rotating self-dual black hole with quasi-periodic oscillations
Cheng Liu, Haiguang Xu, Hoongwah Siew +3
An impressive feature of loop quantum gravity (LQG) is that it can elegantly resolve both the big bang and black hole singularities. By using the Newman-Janis algorithm, a regular…
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…
