Evolution of magnetic field of the Quasar 1604+159 at pc scale
Xu-Zhi Hu, Xiaoyu Hong, Wei Zhao +3
We have analyzed the total intensity, spectral index, linear polarization, and RM distributions at pc scale for the quasar 1604+159. The source was observed in 2002 and 2020 with t…
IGR J12580+0134: A Possible Repeated Partial Tidal Disruption Event Inferred from Late-Time Radio Re-brightenin
Po Ma, Shao-Yu Fu, Linhui Wu +2
Repeating partial tidal disruption events (pTDEs) provide a direct probe of stellar orbits and episodic mass loss around supermassive black holes, but robust identification require…
A candidate field for deep imaging of the Epoch of Reionization observed with MWA
Xueying Zhang, Qian Zheng, Linhui Wu +8
Deep imaging of structures from the Cosmic Dawn (CD) and the Epoch of Reionization (EoR) in five targeted fields is one of the highest priority scientific objectives for the Square…
Is Innovation Becoming Less Disruptive? An Inventory of the Literature
Xiangting Wu, Linhui Wu, Michael Park +2
A growing literature has examined whether innovation is becoming less disruptive, spanning diverse domains and data sources and using a range of methodologies. This paper provides…
A graph-based multimodal framework to predict gentrification
Javad Eshtiyagh, Baotong Zhang, Yujing Sun +2
Gentrification--the transformation of a low-income urban area caused by the influx of affluent residents--has many revitalizing benefits. However, it also poses extremely concernin…
Detection of disk-jet co-precession in a tidal disruption event
Yanan Wang, Zikun Lin, Linhui Wu +46
Theories and simulations predict that intense spacetime curvature near black holes bends the trajectories of light and matter, driving disk and jet precession under relativistic to…
Constraints on the location of -ray emitting region for a sample of blazars with radio core-shift measurements
Linhui Wu, Qingwen Wu, Dahai Yan +2
We model simultaneous or quasi-simultaneous multi-band spectral energy distributions (SEDs) for a sample of 25 blazars that have radio core-shift measurements, where a one-zone lep…
Magnetic Field of the Quasar 1604+159 from Parsec to Kilo-parsec Scale
Xu-Zhi Hu, Xiaoyu Hong, Wei Zhao +3
We present a multi-frequency polarimetric study for the quasar 1604+159. The source was observed at the band with the American Very Long Baseline Array (VLBA) and the , ,…
Formation of giant radio sources in galaxy clusters
Xiaodong Duan, Linhui Wu, Ruiyu Zhang +1
The number of observed giant radio sources (GRSs) has increased significantly in recent years, yet their formation mechanisms remain elusive. The discovery of giant radio galaxies…
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…
Ram-pressure stripped radio tail and two ULXs in the spiral galaxy HCG 97b
Dan Hu, Michal ZajaÄek, Norbert Werner +11
We report LOFAR and VLA detections of extended radio emission in the spiral galaxy HCG 97b, hosted by an X-ray bright galaxy group. The extended radio emission detected at 144 MHz,…
MWA and VLA Observations of Diffuse Radio Lobes in M 87
Linhui Wu, Fu-Guo Xie, Qian Zheng +12
This study investigates the projected, quasi-symmetric -scale diffuse radio lobes surrounding the giant elliptical galaxy M\,87, utilizing well-sampled wideband ($\…
