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 Total and Polarized Radio Emission from the Innermost Jets of a High-Redshift Quasar and a Candidate at Parsec-Scale Resolution
Bence Husvéth, Krisztina É. Gabányi, Tao An +4
High-frequency very long baseline interferometry (VLBI) polarimetry probes synchrotron-emitting plasma closer to the central engines of radio-loud active galactic nuclei (AGNs), bu…
Radio Properties of Narrow-Line and Broad-Line Seyfert 1 Galaxies
K. É. Gabányi, S. Komossa, A. Mezősi +2
Narrow-line Seyfert 1 (NLS1) galaxies host active galactic nuclei (AGN) with narrow optical emission lines of the broad-line region. This is often explained with a relatively lower…
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…
Direct VLBI evidence for a buried AGN in the triple-merger LIRG UGC 2369S
Wancheng Xu, Sándor Frey, Lang Cui +1
UGC 2369S is a luminous infrared galaxy (LIRG) undergoing a late-stage merger in a triple system, where the heavily obscured northern core is suspected to host an active galactic n…
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…
