Scientific paper

FRII radio galaxies are the most powerful jet-driven AGN outbursts in the local universe. Constraints on their hot-gas environments and internal energy densities from X-ray observations suggest that in some cases the energy input from the radio galaxy as it expands is comparable to the binding energy of the hot IGM, so that the radio galaxy should be drastically heating or even unbinding a large amount of the baryonic matter in its environment. At present, however, there are no observations of nearby FRII radio galaxies in poor environments with sufficient sensitivity to observe this process in action. We propose detailed observations of 2 objects with a sensitivity that will allow us to observe the effects of FRII energy input on the temperature, density and entropy structure of their host groups.
