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…
VLBI astrometry of radio stars to link radio and optical celestial reference frames - II. 11 radio stars
Jingdong Zhang, Bo Zhang, Shuangjing Xu +10
The alignment between the radio-based International Celestial Reference Frame (ICRF) and the optical Gaia Celestial Reference Frame (Gaia-CRF) is critical for multi-waveband astron…
