Abstract Jets from the central CD galaxy found within galaxy clusters can propagate to distances of > 100 s of kiloparsecs, thereby interacting with the intracluster medium. X-ray data of the (intracluster) gas in galaxy clusters and their interpretations based on numerical modeling suggest that an additional heating mechanism is required to explain the dynamics and temperature profile in the intracluster medium (ICM). In addition to shock heating, star formation, and supernovae, it is plausible that an additional heating mechanism for the ICM comes from astrophysical jets originating in the cores of radio galaxies. We discuss some aspects of these jets, including the mechanisms of their propagation and energy loss, their constitution, and the non-linear character of their energy loss processes.
