X-Ray and Radio Interactions in the Cores of Cooling Flow Clusters

We present high resolution ROSAT x-ray and radio observations of threecooling flow clusters containing steep spectrum radio sources at their cores.All three systems exhibit strong signs of interaction between the radio plasmaand the hot intracluster medium. Two clusters, A133 and A2626, show enhancedx-ray emission spatially coincident with the radio source whereas the thirdcluster, A2052, exhibits a large region of x-ray excess surrounding much of theradio source. Using 3-D numerical simulations, we show that a perturbed jetpropagating through a cooling flow atmosphere can give rise to amorphous radiomorphologies, particularly in the case where the jet was ``turned off'' andallowed to age passively. In addition, the simulated x-ray surface brightnessproduced both excesses and deficits as seen observationally.Comment: 25 pages, 10 figures, accepted for publication in A
