We present a catalogue of 12CO(J=1-0) and 13CO(J=1-0) molecular clouds in the spatio-velocity range of the Carina Flare supershell, GSH 287+04-17. The data cover a region of ~66 sq…
The Second Survey of the Molecular Clouds in the Large Magellanic Cloud by NANTEN I: Catalog of Molecular Clouds
Yasuo Fukui, Akiko Kawamura, Tetsuhiro Minamidani +8
The second survey of the molecular clouds in 12CO (J = 1-0) was carried out in the Large Magellanic Cloud by NANTEN. The sensitivity of this survey is twice as high as that of the…
Aligned Molecular Clouds towards SS433 and L=348.5 degrees; Possible Evidence for Galactic "Vapor Trail" Created by Relativistic Jet
H. Yamamoto, S. Ito, S. Ishigami +8
We have carried out a detailed analysis of the NANTEN 12CO(J=1-0) dataset in two large areas of ~25 square degrees towards SS433 (l~40 degree) and of ~18 square degrees towards l~3…
Submillimeter Line Emission from LMC N159W: a Dense, Clumpy PDR in a Low Metallicity Environment
J. L. Pineda, N. Mizuno, J. Stutzki +30
Star formation at earlier cosmological times takes place in an interstellar medium with low metallicity. The Large Magellanic Cloud (LMC) is ideally suited to study star formation…
The "Carina Flare" Supershell: Probing the Atomic and Molecular ISM in a Galactic Chimney
J. R. Dawson, N. Mizuno, T. Onishi +2
The "Carina Flare" supershell, GSH 287+04-17, is a molecular supershell originally discovered in 12CO(J=1-0) with the NANTEN 4m telescope. We present the first study of the shell's…
12CO 4-3 and [CI] 1-0 at the centers of NGC 4945 and Circinus
M. Hitschfeld, M. Aravena, C. Kramer +30
Studying molecular gas in the central regions of the star burst galaxies NGC4945 and Circinus enables us to characterize the physical conditions and compare them to previous local…
Clumpy photon-dominated regions in Carina. I. [CI] and mid-J CO lines in two 4'x4' fields
C. Kramer, M. Cubick, M. Roellig +31
The Carina region is an excellent astrophysical laboratory for studying the feedback mechanisms of newly born, very massive stars within their natal giant molecular clouds (GMCs) a…
Sub-millimeter Observations of Giant Molecular Clouds in the Large Magellanic Cloud: Temperature and Density as Determined from J=3-2 and J=1-0 transitions of CO
T. Minamidani, N. Mizuno, Y. Mizuno +26
We have carried out sub-mm 12CO(J=3-2) observations of 6 giant molecular clouds (GMCs) in the Large Magellanic Cloud (LMC) with the ASTE 10m sub-mm telescope at a spatial resolutio…
ASTE Submillimeter Observations of a Young Stellar Object Condensation in Cederblad 110
Masaaki Hiramatsu, Takahiro Hayakawa, Ken'ichi Tatematsu +5
We present results of submillimeter observations of a low-mass young stellar objects (YSOs) condensation in the Cederblad 110 region of the Chamaeleon I dark cloud with Atacama Sub…
