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…
Dense and Warm Molecular Gas between Double Nuclei of the Luminous Infrared Galaxy NGC 6240
K. Nakanishi, S. K. Okumura, K. Kohno +2
High spatial resolution observations of the 12CO(1-0), HCN(1-0), HCO+(1-0), and 13CO(1-0) molecular lines toward the luminous infrared merger NGC 6240 have been performed using the…
Discovery of a Radio Source following the 27 December 2004 Giant Flare from SGR 1806-20
P. B. Cameron, P. Chandra, A. Ray +11
Over a decade ago it was established that the remarkable high energy transients, known as soft gamma-ray repeaters (SGRs), are a Galactic population and originate from neutron star…
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…
NMA CO (J=1-0) Observations of the Halpha/Radio Lobe Galaxy NGC 3079: Gas Dynamics in a Weak Bar Potential and Central Massive Core
J. Koda, Y. Sofue, K. Kohno +4
within 24 lines with 80 characters) We present ^12CO (1-0) observations in the central 4.5 kpc (1 arcmin) of the Halpha/Radio lobe galaxy NGC 3079 with the Nobeyama Millimeter Arra…
Dense Molecular Gas and Star Formation in Nearby Seyfert Galaxies
K. Kohno, S. Matsushita, B. Vila-Vilaro +5
An imaging survey of CO(1-0), HCN(1-0), and HCO(1-0) lines in the centers of nearby Seyfert galaxies has been conducted using the Nobeyama Millimeter Array and the RAINBOW inte…
Formation of a Massive Black Hole at the Center of the Superbubble in M82
S. Matsushita, R. Kawabe, H. Matsumoto +5
We performed 12CO(1-0), 13CO(1-0), and HCN(1-0) interferometric observations of the central region (about 450 pc in radius) of M82 with the Nobeyama Millimeter Array, and have succ…
Ultra-High-Density Molecular Core and Warped Nuclear Disk in the Deep Potential of Radio-Lobe Galaxy NGC 3079
Y. Sofue, J. Koda, K. Kohno +4
We have performed high-resolution synthesis observations of the 12CO (J=1-0) line emission from the radio lobe edge-on spiral NGC 3079 using a 7-element mm-wave interferometer at N…
Bar-driven Transport of Molecular Gas to Galactic Centers and Its Consequences
K. Sakamoto, S. K. Okumura, S. Ishizuki +1
We study the characteristics of molecular gas in the central regions of spiral galaxies on the basis of our CO(J=1-0) imaging survey of 20 nearby spiral galaxies using the NRO and…
Radial Transport of Molecular Gas to the Nuclei of Spiral Galaxies
K. Sakamoto, S. K. Okumura, S. Ishizuki +1
The NRO/OVRO imaging survey of molecular gas in 20 spiral galaxies is used to test the theoretical predictions on bar-driven gas transport, bar dissolution, and bulge evolution. In…
