Research Abstract

Based on the sub-millimeter wave observations to the nearby galaxies and the Magellanic Clouds with ASTE telescope, the densities and temperatures of the dense regions of the giant molecular clouds were derived accurately, and the relationship between the physical properties and star formation activities of the dense molecular clouds were established quantitatively. In addition, while the effect of the sweeping up by the giant shells in the galaxies may play an important role in formation of the molecular cloud, the ionized atomic hydrogen regions have a direct triggering on the massive star formation secondary in molecular clouds. This shows that the global phenomenon and local star formation can be combined and related each other.
