Research Abstract |
The 20-GHz observing system of the Tsukuba 32-telescope was much improved in the frequency coverage and sensitivity to make observations of six lines of ammonia molecules simultaneously. Using the system, Orion Molecular Clouds were observed in ammonia lines, resulting that the clouds have been made warm by outside massive stars. Ammonia along the Milky Way galaxy was also surveyed to determine the temperature and make its heating mechanism clear.
