dc.description.abstractWe present high-resolution ROSAT X-ray and radio observations of three cooling Ñow clusters containing steep-spectrum radio sources at their cores. All three systems exhibit strong signs of interaction between the radio plasma and the hot intracluster medium. Two clusters, A133 and A2626, show enhanced X-ray emission spatially coincident with the radio source, whereas the third cluster, A2052, exhibits a large region of X-ray excess surrounding much of the radio source. Using three-dimensional numerical simulations, we show that a perturbed jet propagating through a cooling Ñow atmosphere can give rise to amorphous radio morphologies, particularly in the case where the jet was turned o ÏÏ and allowed to age passively. In addition, the simulated X-ray surface brightness produced both excesses and deÐcits as seen observationally.eng
