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…
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…
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…
Synchrotron Self-Absorption Spectral Modeling Reveals a Magnetically Driven Shock-in-Jet Scenario in Blazar 1156+295
Wancheng Xu, Lang Cui, Tao An +6
Unveiling the launching and driving mechanisms of powerful jets in active galactic nuclei (AGNs) is crucial for understanding the co-evolution of supermassive black holes (SMBHs) a…
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…
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…
Solid Identification of Extragalactic Gamma-Ray Source Using High-Resolution Radio Interferometric Observation
K. É. Gabányi, S. Frey, K. Perger +1
The dominant fraction of the extragalactic -ray sources are blazars, active galactic nuclei with jets inclined at a small angle to the line of sight. Apart from blazars, a few d…
VLBI Analysis of a Potential High-Energy Neutrino Emitter Blazar
Janka Kőmíves, Krisztina Éva Gabányi, Sándor Frey +1
Recent studies suggest that high-energy neutrinos can be produced in the jets of blazars, radio-loud active galactic nuclei (AGN) with jets pointing close to the line of sight. Due…
Follow-up on the Supermassive Black Hole Binary Candidate J1048+7143: Successful Prediction of the Next Gamma-ray Flare and Refined Binary Parameters in the Framework of Jet Precession Model
Emma Kun, Ilja Jaroschewski, Julia Becker Tjus +6
Analyzing single-dish and VLBI radio, as well as \textit{Fermi}-LAT -ray observations, we explained the three major flares in the -ray light curve of FSRQ J1048+7143 with the…
