Telescope and other projects

The 1.85m mm/sub-mm telescope is deveropped and operated by Osaka Prefecture University, together with Tokyo Gakugei University. It is installed at the Nobeyama Radio Observatory. The telescope is designed to carry out the large scale survey which covers whole extents of (Giant) Molecular Clouds. For more detail on the instruments and project, refer to Onishi et al. (2013) and other references.
