Giant Radio Galaxies: Testing the Extremes of AGN Feedback
Abstract
Giant radio galaxies (GRGs), whose lobes can extend to Mpc scales, tend to avoid rich environments. It is rare to find them in the centers of galaxy clusters, but in this environment they raise important questions for AGN feedback models. With most of the energy of the jets dissipated in lobes far outside the cool core, do such systems represent a failure mode of feedback? If not, how do these sources maintain the thermal balance of the ICM? We propose to observe two nearby cluster-central GRGs, using Chandra's exquisite spatial resolution to characterize their halos, examine conditions in their cool cores and search for evidence of interactions between the intra-cluster medium and the jets of these exceptionally powerful, long-lived radio galaxies.
