Jet reorientation revealed by intermittent jet activity in radio galaxy 0954+556
Ai-Ling Zeng, Wei Zhao, Jun Yang +9
Intermittent jet activity of AGNs is a common phenomenon, whereas significant jet reorientation during episodic jet activity in relatively young radio galaxies are rarely reported.…
An Ejection Event Captured by VLBI During the Outburst of Swift J1727.81613
Hongmin Cao, Jun Yang, Sándor Frey +9
We observed a newly-discovered Galactic black hole X-ray binary Swift J1727.81613 with the European Very Long Baseline Interferometry Network (EVN) at 5 GHz. The observation was…
Analysis of Jet Dynamics and Collimation Characteristics of 0241+622 on Parsec Scales
Haitian Shang, Wei Zhao, Xiaoyu Hong +1
We conducted a detailed analysis of the jet structure and dynamics of the source 0241+622 on milliarcsecond (mas) scales. We stacked images from multiple epochs to better recover t…
Unveiling the Complex Jet Dynamics in the Blazar 2021+317 through Multi-Epoch VLBI Observations
Haitian Shang, Wei Zhao, Xiaoyu Hong +4
We present an investigation of the compact structure of the AGN 2021+317 based on multi-epoch Very Long Baseline Interferometry (VLBI) observations at 15, 22, and 43 GHz in the per…
Proper Motion and Natal Kick in the Galactic Black Hole X-ray Binary AT2019wey
Lang Cui, Pengfei Jiang, Tao An +9
Understanding the formation mechanisms of stellar-mass black holes in X-ray binaries (BHXBs) remains a fundamental challenge in astrophysics. The natal kick velocities imparted dur…
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…
A centi-pc-scale compact radio core in the nearby galaxy M60
Xiaofeng Li, Jun Yang, Xiaopeng Cheng +7
M60, an elliptical galaxy located 16.5~Mpc away, has an active nucleus with a very low luminosity and an extremely low accretion rate. Its central supermassive black hole has a mas…
Compact Bright Radio-loud AGNs -- III. A Large VLBA Survey at 43 GHz
X. -P. Cheng, T. An, S. Frey +12
We present the observational results from the 43-GHz Very Long Baseline Array (VLBA) observations of 124 compact radio-loud active galactic nuclei (AGNs) that were conducted betwee…
