SMA CO(J=6-5) and 435 micron interferometric imaging of the nuclear region of Arp 220
Satoki Matsushita, Daisuke Iono, Glen R. Petitpas +11
We have used the Submillimeter Array (SMA) to make the first interferometric observations (beam size ~1") of the 12CO J=6-5 line and 435 micron (690 GHz) continuum emission toward…
Microstructure and kinematics of H2O masers in the massive star forming region IRAS 06061+2151
K. Motogi, Y. Watanabe, K. Sorai +14
We have made multi-epoch VLBI observations of H2O maser emission in the massive star forming region IRAS 06061+2151 with the Japanese VLBI network (JVN) from 2005 May to 2007 Octob…
Interferometric 12CO(J=2-1) image of the Nuclear Region of Seyfert 1 Galaxy NGC 1097
Pei-Ying Hsieh, Satoki Matsushita, Jeremy Lim +2
We have mapped the central region of the Seyfert 1 galaxy NGC 1097 in 12CO(J=2-1) with the Submillieter Array (SMA). The 12CO(J=2-1) map shows a central concentration and a surroun…
A Synchronized Variation of the 6.7 GHz Methanol Maser in Cepheus A
Koichiro Sugiyama, Kenta Fujisawa, Akihiro Doi +5
We present the results of daily monitoring of 6.7 GHz methanol maser in Cepheus A (Cep A) using Yamaguchi 32-m radio telescope as well as the results of imaging observations conduc…
Positional Coincidence of H2O Maser and a Plasma Obscuring Torus in Radio Galaxy NGC 1052
Satoko Sawada-Satoh, Seiji Kameno, Kayoko Nakamura +3
We present multi-frequency simultaneous VLBA observations at 15, 22 and 43 GHz towards the nucleus of the nearby radio galaxy NGC 1052. These three continuum images reveal a double…
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,…
