Distinct Jet Properties in the X-Ray-Obscured State of GRS 1915+105
Xi Yan, Lang Cui, Sergei Trushkin +6
GRS 1915+105 has remained in an X-ray-obscured state since its transition from a long-lasting unobscured state in 2019. We report on 6.7-GHz East Asia VLBI Network observations of…
Magnetic rigidity reveals the PeVatron acceleration region in SS 433
Jie Liao, Wancheng Xu, Lang Cui +10
PeVatrons are cosmic accelerators capable of driving particles to petaelectronvolt (PeV) energies. Recently, microquasar jets have emerged as compelling Galactic PeVatron candidate…
The First Measurement of Jet Collimation Profiles in an X-ray Binary: the Case of SS 433
Xi Yan, Lang Cui, Zsolt Paragi +1
While significant progress has been achieved in active galactic nuclei (AGN), jet collimation profiles in X-ray binaries (XRBs) have not been directly measured. Here we report the…
Dual AGN and Multiple SMBH Systems in the Era of SKAO
Q. D'Amato, L. Cui, R. Deane +23
We present a radio-oriented review of current strategies for the detection and characterization of dual active galactic nuclei (DAGN) and supermassive black hole binaries (SMBHBs),…
Discovery of Unusual Jet Orientation Variations in the Microquasar GRS 1915+105
Xi Yan, Lang Cui, Wu Jiang +6
We report large day-timescale variations in the orientation of the southeast--northwest jet in the prototype microquasar GRS 1915+105. These results are based on three-epoch East A…
A large misalignment between continuous jet and discrete ejecta in microquasar GRS 1915+105 during its obscured phase
Wu Jiang, Xi Yan, Zhen Yan +3
We report a large misalignment between the continuous jet and the discrete ejecta in GRS 1915+105, detected in April 2023 with the East Asian VLBI network (EAVN). Two-sided ejecta…
Sub-Parsec Acceleration and Collimation of NGC 4261's Twin Jets
Xi Yan, Lang Cui, Kazuhiro Hada +6
We report the first robust evidence for a co-spatial sub-parsec acceleration and collimation zone (ACZ) in the twin jets of the nearby low-luminosity active galactic nucleus (LLAGN…
Multi-frequency Very Long Baseline Interferometry Study of Emission and Absorption in the Two-Sided Jets of NGC 3998
Xi Yan, Lang Cui, Luis C. Ho
We present the multi-frequency, multi-epoch Very Long Baseline Interferometry (VLBI) study of the two-sided jets in the low-luminosity active galactic nucleus NGC 3998, where physi…
The orbital period of the long-period and colliding-wind binary WR 146 from radio interferometry of the shock cone
Shiming Wen, Bo Zhang, Shuangjing Xu +8
We report the first measurement of the orbital period of a long-period colliding-wind binary (CWB) system WR 146, derived by tracing the rotational morphology of its wind-colliding…
