Signature of iron line profile from a Kerr-like wormhole
Cheng Liu, Hoongwah Siew, Hong-Xuan Jiang +2
Broad, skewed iron K emission lines in the X-ray spectra of accreting black holes encode key information about the spacetime geometry of the innermost disk. While the Kerr metri…
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…
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…
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…
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…
