We present CO(3–2) emission observations toward the 3 ′ × 3 ′ (or 20 × 20 kpc at a distance of 23 Mpc) region of the southern barred spiral galaxy NGC 986 using the Atacama Submillimeter...

A Search for CO(J=3-2) Emission from the Host Galaxy of GRB 980425 with the Atacama Submillimeter Telescope Experiment (2007)

Hatsukade, Bunyo, Kohno, Kotaro, Endo, Akira, Tosaki, Tomoka, Ohta, Kouji, Sakamoto, Seiichi, ...

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 galaxy covering...

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 (2007)

Muraoka, Kazuyuki, Kohno, Kotaro, Tosaki, Tomoka, Kuno, Nario, Nakanishi, Kouichiro, Sorai, Kazuo, ...

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 the nearby barred...

Carbon isotope ratio in 12CO/13CO toward local molecular clouds with near-infrared high-resolution spectroscopy of vibrational transition bands (2003)

Goto, Miwa, Usuda, Tomonori, Takato, Naruhisa, Hayashi, Masa, Sakamoto, Seiichi, Gaessler, W., ...

We report the carbon monoxide isotope ratio in local molecular clouds toward LkH**alpha; 101, AFGL 490, and Mon R2 IRS 3. The vibrational transition bands of 12CO **nu;=2**lt;--0 and 13CO...
