Sub-Parsec-Scale Jet-Driven Water Maser with Possible Gravitational Acceleration in the Radio Galaxy NGC 1052
Seiji Kameno, Yuichi Harikane, Satoko Sawada-Satoh +5
We report sub-pc-scale observations of the 321-GHz HO emission line in the radio galaxy NGC 1052. The HO line emitter size is constrained in milliarcsec distributed…
VLBI Monitoring of 3C 84 in Gamma-ray Active Phase
H. Nagai, K. Suzuki, K. Asada +5
We report multi-epoch Very Long Baseline Interferometry (VLBI) study of the innermost jet of 3C 84. We carried out 14-epoch VLBI observations during 2006-2009 with the Japanese VLB…
The Dense Plasma Torus Around the Nucleus of an Active Galaxy NGC 1052
S. Kameno, S. Sawada-Satoh, M. Inoue +2
A subparsec-scale dense plasma torus around an active galactic nucleus (AGN) is unveiled. We report on very-long-baseline interferometry (VLBI) observations at 2.3, 8.4, and 15.4 G…
Superluminal motion in a compact steep spectrum radio source 3C 138
Z. -Q. Shen, D. R. Jiang, S. Kameno +1
We present the results of 5 GHz VLBI observations of a compact steep spectrum source 3C 138. The data are consistent with the western end being the location of the central activity…
Sub-parsec-scale Accleration of the Radio Jet in the Powerful Radio Galaxy NGC 6251
H. Sudou, Y. Taniguchi, Y. Ohyama +5
In order to investigate the genesis of powerful radio jet, we have mapped the central 10 pc region of the nearby radio galaxy NGC 6251 with a 0.2 pc resolution using Very Long Base…
High Resolution VSOP Imaging of a Southern Blazar PKS 1921-293 at 1.6 GHz
Z. -Q. Shen, P. G. Edwards, J. E. J. Lovell +3
We present a high resolution 1.6 GHz VSOP image of the southern blazar PKS 1921-293. The image shows a typical core-jet morphology, consistent with ground-based VLBI images. Howeve…
