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…
Molecular Gas Distribution in Barred and Non-Barred Galaxies along the Hubble Sequence
S. Komugi, Y. Sofue, K. Kohno +4
We present results from a survey of 12CO(J=1-0) spectra obtained for the central regions of 68 nearby galaxies at an angular resolution of 16 arcseconds using the Nobeyama Radio Ob…
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…
ASTE CO(3--2) Observations of the Southern Barred Spiral Galaxy NGC 986: a Large Gaseous Bar Filled with Dense Molecular Medium
K. Kohno, T. Tosaki, R. Miura +20
We present CO(3-2) emission observations toward the 3'x3' (or 20x20kpc at a distance of 23Mpc) region of the southern barred spiral galaxy NGC 986 using the Atacama Submillimeter T…
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…
A Revised Estimate of the CO (J=1-0) Emission from the Host Galaxy of GRB 030329 Using the Nobeyama Millimeter Array
Akira Endo, Kotaro Kohno, Bunyo Hatsukade +9
A sensitive observation of the CO (J=1-0) molecular line emission in the host galaxy of GRB 030329 (z =0.1685) has been performed using the Nobeyama Millimeter Array in order to de…
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…
Nobeyama Millimeter Array Observations of GRB 030329: a Decay of Afterglow with Bumps and Molecular Gas in the Host Galaxy
K. Kohno, T. Tosaki, T. Okuda +12
Nobeyama Millimeter Array was used to observe millimeter-wave afterglow of GRB 030329 at 93 GHz and 141 GHz from 2003 April 6 to 2003 May 30. A sensitive search for CO(J=1-0) emiss…
