Environments and environmental impact of local FRII radio galaxies

FRII radio galaxies are the most powerful jetdriven AGN outbursts in the localuniverse. Constraints on their hotgas environments and internal energydensities from Xray observations suggest that in some cases the energy inputfrom the radio galaxy as it expands is comparable to the binding energy of thehot IGM, so that the radio galaxy should be drastically heating or evenunbinding a large amount of the baryonic matter in its environment. At present,however, there are no observations of nearby FRII radio galaxies in poorenvironments with sufficient sensitivity to observe this process in action. Wepropose detailed observations of 2 objects with a sensitivity that will allow usto observe the effects of FRII energy input on the temperature, density and entropy structure of their host groups. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
