Research Abstract

We have carried out various observations of molecular clouds towards nearby star forming regions, the Galactic plane, and the Large Magellanic Clouds with NANTEN2 submm telescope and Mopra mm telescope. We have also make use of the previous survey results by NANTEN and obtained the detailed physical properties of the molecular clouds. The new data taken by the Infrared Satellites, Planck and Herschel was used to obtain interstellar dust emission as well as point sources. Point source catalog was combined with Spitzer point source catalogs to determine the young stellar objects. All there datasets were used to carryout comprehensive study of molecular clouds, Interstellar dust and star formation processes. There results are used to propose observations of star forming regions by ALMA and our successive proposal started to give us high resolution and high sensitivity data of a nearby star forming region.
