East Asian VLBI Network astrometry toward the star-forming region G040.96+02.48 in the Extreme Outer Galaxy

Xianjin Shen, Zehao Lin, Nobuyuki Sakai +18

Accurate astrometric measurements for star-forming regions located on the far side of the Milky Way remain scarce. In this work, we present the astrometric results for a 22\,GHz wa…

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…

First Detection of Radio Emission from the Intermediate Mass Black Hole in POX 52: Deep Multi-Band Observations with ATCA and VLA

Qi Yuan, Hengxiao Guo, Minfeng Gu +14

We present the first multi-band centimeter detection of POX 52, a nearby dwarf galaxy believed to habor a robust intermediate mass black hole (IMBH). We conducted the deep observat…

Tracking the jet-like corona of black hole Swift J1727.8-1613 during a flare state through Type-C quasi-periodic oscillations

Jie Liao, Ning Chang, Lang Cui +10

Type-C quasi-periodic oscillations (QPOs) in black hole X-ray transients typically manifest in the low-hard and hard-intermediate states. This study presents a detailed spectral an…

Very Long Baseline Array Observations of Parsec-scale Radio Emission in Dual Active Galactic Nuclei

Wancheng Xu, Lang Cui, Xiang Liu +11

It is believed that dual active galactic nuclei (dual AGN) will form during galaxies merge. Studying dual-AGN emission can provide valuable insights into galaxy merging and evoluti…

VLBI detection of the AE Aqr twin, LAMOST J024048.51+195226.9

Pengfei Jiang, Lang Cui, Xiang Liu +8

LAMOST J024048.51+195226.9 (J0240+1952) was recently identified as the second AE Aquarii (AE Aqr)-type cataclysmic variable, possessing the fastest known rotating white dwarf. We p…

Correlation analysis between several observables of OJ 287 radio jet

Qi Yuan, Ming Zhang, Xiang Liu +2

We collected the archival data of blazar OJ~287 from heterogeneous very long baseline interferometry (VLBI) monitoring programs at 2.3 GHz, 8.6 GHz, 15 GHz and 43 GHz. The data red…
