Nobeyama Millimeter Array Observations of the Nuclear Starburst of M83: A GMA Scale Correlation between Dense Gas Fraction and Star Formation Efficiency
Kazuyuki Muraoka, Kotaro Kohno, Tomoka Tosaki +6
We present aperture synthesis high-resolution (~ 7" x 3") observations in CO(J=1-0) line, HCN(J=1-0) line, and 95 GHz continuum emission toward the central (~ 1.5 kpc) region of th…
Tracing star formation in galaxies with molecular line and continuum observations
K. Kohno, K. Muraoka, B. Hatsukade +14
We report our recent progress on extragalactic spectroscopic and continuum observations, including HCN(J=1-0), HCO(J=1-0), and CN(N=1-0) imaging surveys of local Seyfert and st…
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…
A Search for CO(J=3-2) Emission from the Host Galaxy of GRB 980425 with the Atacama Submillimeter Telescope Experiment
Bunyo Hatsukade, Kotaro Kohno, Akira Endo +14
We report on a deep search for CO(J=3-2) line emission from the host galaxy of GRB 980425 with the Atacama Submillimeter Telescope Experiment (ASTE). We observed five points of the…
