| Research Abstract |
We studied clusters of galaxies from the macroscopic and microscopic viewpoints. We revealed the dynamics of hot intracluster gas and cosmic-rays through observations with an X-ray satellite and a radio telescope. We also found that cosmic-rays take a long time to escape from acceleration sources.
