Results of HC 3 N observations of 15 dense molecular cloud cores, associated with bright IRAS sources in the outer Galaxy, are reported. HC 3 N column densities and emission region sizes have been calculated. The J =10-9 line analysis have been performed, along with the J =12-11 and J =5-4 data in the framework of the microturbulent isothermal model. The logarithms of densities found for 4 objects lie in the range: 5.5-5.9 being ∼(0.5-1) orders of magnitude higher than mean densities. Possible models for these objects should incorporate inhomogeneous density structure.

Les observations radio de 33 galaxies sud, de flux IR > 4.5 Jy et de luminosite IR intrinseque > 1O 11 L ○. , sont presentees. Une emission CO (1-0) est detectee dans 28 de ces galaxies. Les profils de CO sont analyses. Le centroide des vitesses heliocentriques du profil CO, l'intensite totale de la raie CO et la masse totale de l'hydrogene moleculaire sont determines pour chacune des 28 galaxies.

Results of the ESO-SEST Key Programme on CO in the Magellanic Clouds. I : A survey of CO in the LMC and the SMC

Astronomy and Astrophysics (1993)

As the first part of the ESO-Swedish SEST Key Programme on CO in the Magellanic Clouds, we have observed 12 CO J=1-0 towards 92 positions in the LMC and 42 positions in the SMC. In the SMC we searched for emission form H II regions, dark clouds and IRAS infrared sources. The generally negative detection rate of non-IRAS sources in the SMC led to an LMC source selection based on the IRAS results. In both galaxies, CO was detected towards the majority of sources observed. We also observed 13 CO J=1-0 towards the brighter 12 CO sources in the LMC (37) and SMC (9). Compared to the strength of CO lines observed in the Milky Way Galaxy with identical linear resolutions, velocity-integrated CO emission is weaker by at least a factor of three in the LMC sources and an order of magnitude in the SMC sources
