Abstract

We present high-resolution X-ray observations of the cluster A2029 with the ROSAT HRI which confirm the presence of a cooling flow, despite the lack of optical line emission or evidence for recent star formation. The cooling rate and radius are M(c) almost-equal-to 370 M. yr-1 and r(c) almost-equal-to 230 kpc, respectively. Emission from the inner cooling flow is dominated by a number of X-ray-emitting filaments. This may be the first case where such inhomogeneities have been clearly resolved. The filaments may be supported in part by magnetic fields and may be connected with the filaments of very strong Faraday rotation seen in several nearly cooling flows.
