| Outline of Final Research Achievements |
We searched for helically moving HI clouds using Galactic All Sky Survey data obtained with Parkes 64m telescope in Australia in order to examine if the Galactic magnetic field is amplified with Galactic dynamo process. As a result, we found that they can be explained as magnetically floating loops and the emerging rate is comparable to a predicted value by the Galactic dynamo hypothesis. We developed an HI observation system for JAXA Usuda 64-m telescope to conduct high-velocity resolution observation for a helically moving HI cloud.
