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
The paper presents the first direct measurement of jet collimation profiles in the X-ray binary SS 433 using very long baseline interferometry, revealing a quasi‑parabolic jet shap…
Distinct Jet Properties in the X-Ray-Obscured State of GRS 1915+105
Xi Yan, Lang Cui, Sergei Trushkin +6
The paper reports VLBI observations of the microquasar GRS 1915+105 during its X‑ray‑obscured state, revealing slower, non‑relativistic jets with distinct morphologies compared to…
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…
