Mapping Observations of 6.7 GHz Methanol Masers with Japanese VLBI Network
Koichiro Sugiyama, Kenta Fujisawa, Akihiro Doi +5
We have observed 13 methanol maser sources associated with massive star-forming regions; W3(OH), Mon R2, S 255, W 33A, IRAS 18151-1208, G 24.78+0.08, G 29.95-0.02, IRAS 18556+0136,…
The 2006 Radio Outburst of a Microquasar Cyg X-3: Observation and Data
M. Tsuboi, T. Tosaki, N. Kuno +22
We present the results of the multi-frequency observations of radio outburst of the microquasar Cyg X-3 in February and March 2006 with the Nobeyama 45-m telescope, the Nobeyama Mi…
Verification of the Effectiveness of VSOP-2 Phase Referencing with a Newly Developed Simulation Tool, ARIS
Yoshiharu Asaki, Hiroshi Sudou, Yusuke Kono +8
The next-generation space VLBI mission, VSOP-2, is expected to provide unprecedented spatial resolutions at 8.4, 22, and 43GHz. In this report, phase referencing with VSOP-2 is exa…
Japanese VLBI Network observations of radio-loud narrow-line Seyfert 1 galaxies
Akihiro Doi, Kenta Fujisawa, Makoto Inoue +20
We performed phase-reference very long baseline interferometry (VLBI) observations on five radio-loud narrow-line Seyfert 1 galaxies (NLS1s) at 8.4 GHz with the Japanese VLBI Netwo…
