| Research Abstract |
Observations of high transition CO line have been carried out toward Galactic molecular loops 1 and 2 in the Galactic center with NANTEN2 and ASTE telescope. Physical parameters such as temperature, density and kinematics of molecular clouds associated to the loops are revealed. This indicates that foot points of the loops are possibly one of origins of high temperature and high velocity dispersion of the clouds in the Galactic center region. In addition, 13 loops candidates are identified by large scale search toward the Galactic center. Numerical simulation has revealed the process of formation, nature and distribution of the loops.
