The Interaction of AGN Jets with the Intracluster Medium(Poster)

- 論文の詳細を見る
Chandra revealed that many galaxy clusters exhibit an interaction of AGN jets with intracluster medium (ICM). For this reason, they are thought to supply a large amount of heat energy to the ICM so that the cooling flow (CF) is restricted. We analyzed 2A 0335+096 and Abell 2199 in detail. As a result, we found that radio jets do not have enough energy to reduce the overall radiative cooling. We also studied the hot gas cavities of NGC 4636 and found a significant increase in temperature and absorption column density around cavities. However, the energy of a gas disturbance is not large in comparison with the clusters. These results indicate that the activity of most of the radio galaxies has faded, and thus they cannot supply a significant amount of heat energy to the ICM.
