Starbursting Nuclear CO Disks of Early-type Spiral Galaxies
J. Koda, T. Okuda, K. Nakanishi +4
We have initiated the first CO interferometer survey of early-type spiral galaxies (S0-Sab). We observed five early-type spiral galaxies with HII nuclei (indicating circumnuclear s…
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…
Starburst at the Expanding Molecular Superbubble in M82: Self-Induced Starburst at the Inner Edge of the Superbubble
Satoki Matsushita, Ryohei Kawabe, Kotaro Kohno +3
We present high spatial resolution (2.3"x1.9" or 43 pc x 36 pc at D = 3.9 Mpc) 100 GHz millimeter-wave continuum emission observations with the Nobeyama Millimeter Array toward an…
Near-infrared and Millimeter Constraints on the Nuclear Energy Source of the Infrared Luminous Galaxy NGC 4418
Masatoshi Imanishi, Kouichiro Nakanishi, Nario Kuno +1
We present near-infrared and millimeter investigations of the nucleus of the infrared luminous galaxy NGC 4418, which previous observations suggest possesses a powerful buried AGN.…
Virgo High-Resolution CO Survey IV. Spiral-Driven Gas Dynamics in the Non-Barred Seyfert Galaxy NGC 4501
Sachiko Onodera, Jin Koda, Yoshiaki Sofue +1
We report on high-resolution interferometer observations of the 12CO(J=1-0) emission in the central 5 kpc region of the Seyfert 2 galaxy NGC 4501. The observations were made using…
