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…

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…

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…
