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…

Multi-frequency Very Long Baseline Interferometry Study of Emission and Absorption in the Two-Sided Jets of NGC 3998
Xi Yan, Lang Cui, Luis C. Ho
We present the multi-frequency, multi-epoch Very Long Baseline Interferometry (VLBI) study of the two-sided jets in the low-luminosity active galactic nucleus NGC 3998, where physi…

Magnetically Driven Relativistic Jet in the High-Redshift Blazar OH~471
S. Guo, T. An, Y. Liu +15
Context : Understanding the mechanisms that launch and shape powerful relativistic jets from supermassive black holes (SMBHs) in high-redshift active galactic nuclei (AGN) is cruci…
