Observational Evidence of a Centi-parsec Supermassive Black Hole Binary Existing in the Nearby Galaxy M81

Autor: Jiang, Wu, Shen, Zhiqiang, Martí-Vidal, Ivan, Yan, Zhen, Huang, Lei, Gold, Roman, Li, Ya-Ping, Xie, Fuguo, Kawaguchi, Noriyuki

Studying a centi-parsec supermassive black hole binary (SMBHB) would allow us to explore a new parameter space in active galactic nuclei, and these objects are also potential sources of gravitational waves. We report evidence that an SMBHB with an or

Kinematics and Collimation of the Two-Sided Jets in NGC 4261: VLBI Study on Sub-parsec Scales

Autor: Yan, Xi, Lu, Ru-Sen, Jiang, Wu, Krichbaum, Thomas P., Shen, Zhi-Qiang

We report multi-frequency VLBI studies of the sub-parsec scale structure of the two-sided jet in the nearby radio galaxy NGC 4261. Our analyses include new observations using the Source Frequency Phase Referencing technique with the Very Long Baselin
