On-The-Fly Observing System of the Nobeyama 45-m and ASTE 10-m Telescopes
Tsuyoshi Sawada, Norio Ikeda, Kazuyoshi Sunada +10
We have developed spectral line On-The-Fly (OTF) observing mode for the Nobeyama Radio Observatory 45-m and the Atacama Submillimeter Telescope Experiment 10-m telescopes. Sets of…
Central Spiral Structure of Molecular Gas in Maffei 2
Nario Kuno, Kouichiro Nakanishi, Kazuo Sorai +1
Distribution and kinematics of molecular gas in the central region of the barred spiral galaxy Maffei 2 were investigated using a data set of 12CO(1-0), 12CO(2-1), CS(2-1) lines an…
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…
Arc-like distribution of high CO(J=3-2)/CO(J=1-0) ratio gas surrounding the central star cluster of the supergiant HII region NGC 604
T. Tosaki, R. Miura, T. Sawada +5
We report the discovery of a high CO(J=3-2)/CO(J=1-0) ratio gas with an arc-like distribution (``high-ratio gas arc'') surrounding the central star cluster of the supergiant HII re…
Nobeyama CO Atlas of Nearby Spiral Galaxies: Distribution of Molecular Gas in Barred and Non-barred Spiral Galaxies
N. Kuno, N. Sato, H. Nakanishi +7
The data from a CO(1 - 0) mapping survey of 40 nearby spiral galaxies performed with the Nobeyama 45-m telescope are presented. The criteria of the sample selection were (1) RC3 mo…
ASTE CO(3-2) Observations of the Barred Spiral Galaxy M 83: I. Correlation between CO(3-2)/CO(1-0) Ratios and Star Formation Efficiencies
Kazuyuki Muraoka, Kotaro Kohno, Tomoka Tosaki +14
We present CO(J=3-2) emission observations with the Atacama Submillimeter Telescope Experiment (ASTE) toward the 5' x 5' (or 6.6 x 6.6 kpc at the distance D = 4.5 Mpc) region of th…
