An Approach Detecting the Event Horizon of Sgr A*
Makoto Miyoshi, Seiji Kameno, Jose K. Ishituka +3
Imaging the vicinity of a black hole is one of the ultimate goals of VLBI astronomy. The closest massive black hole, Sgr A*, located at the Galactic center, is the leading candidat…
On the Near-term Space VLBI Mission VSOP-2
H. Hirabayashi, Y. Murata, P. G. Edwards +6
A second generation near-term space VLBI mission, VSOP-2, is being planned for a launch in 2010 or soon after. The scientific objectives are very high angular resolution imaging of…
Multi-Frequency VLBI Observations of GHz-Peaked Spectrum Sources
S. Kameno, M. Inoue, Z. -Q. Shen +2
We report results of pentachromatic VLBI survey for 18 GHz-peaked spectrum sources. Spectral fitting at every pixel across five frequencies allows us to illustrate distribution of…
An Approach Detecting the Event Horizon of SgrA*
M. Miyoshi
Imaging the vicinity of black hole is one of the ultimate goals of VLBI astronomy. The closest massive black hole, SgrA*, located at Galactic center is the leading candidate for su…
The VSOP 2 mission: Imaging capabilities
R. Dodson, H. Hirabayashi, Y. Murata +4
Given the scientific goals of VSOP-2, including the possibility of observations of the shadows of black holes, we have investigated the fidelity of the recovered images given a typ…
Detection of the VLBI-scale Counter Jet in NGC 6251
H. Sudou, Y. Taniguchi, Y. Ohyama +5
Mapping the central 5 pc region of the nearby radio galaxy NGC 6251 with a 0.2 pc resolution using VLBI at two radio frequencies, 5 GHz and 15 GHz, we have found the sub-pc-scale c…
