| Outline of Final Research Achievements |
Galaxy clusters are the largest celestial bodies in the Universe. The clusters and the massive black holes at their center have evolved with mutual influence. We investigated the interaction mechanisms. In terms of theory, we showed that the black holes heat the surrounding gas as jets and cosmic rays accelerated near them diffuse into the interstellar space. From the viewpoint of observation, firstly, our radio observations showed that the jet generated around the black hole interacts with the surrounding gas, stirring it and affecting the gas accretion toward the black hole. Our X-ray observations revealed the process on how heavy elements are released from galaxies due to the activity of black holes.
