Central radio sources and the X-ray-emitting intracluster medium (ICM) in clusters of galaxies have a profound effect on one another. The ICM confines and distorts the radio lobes, while the radio lobes "blow bubbles" in the hot ICM. These types of interactions can be studied in detail in the bright centers of cooling flow clusters using observations from Chandra. The radio sources may offset some of the cooling at the centers of clusters. We will present results of the analysis of Chandra data of the radio source / ICM interaction in the cooling flow cluster Abell 262. There is a clear bubble in the ICM coincident with the eastern radio lobe. The gas surrounding the bubble is cool, with no evidence of current strong shocks in the system, so if the radio source is providing heat to the ICM, it is not through strong shocks. We will also present results on the chemical abundance distribution in the cluster, and the correspondence of emission from cooler gas (as measured by H-alpha and [NII] lines) with features seen in the X-ray. Support for E. L. B. was provided by NASA through the Chandra Fellowship Program, grant award number PF1-20017, under NASA contract number NAS8-39073.
