We present the results of a Chandra observation of the cooling core clusterAbell 2063. Spectral analysis shows that there is cool gas (2 keV) associatedwith the cluster core, which is more than a factor of 2 cooler than the outercluster gas (4.1 keV). There also is spectral evidence for a weak cooling flow,Mdot ~ 20 Msun/yr. The cluster exhibits a complex structure in the center thatconsists of several bright knots of emission, a depression in the emission tothe north of the center of the cluster, and a shell of emission surrounding it.The depression in the X-ray emission is coincident with the position of thenorth-eastern radio lobe of the radio source associated with thecluster-central galaxy. The shell surrounding this region appears to be hotter,which may be the result of a shock that has been driven into the gas by theradio source. The power output of the radio source appears to be sufficient tooffset the cooling flow, and heating of the gas through shocks is a possibleexplanation of how the energy transfer is established.Comment: Astrophysical Jounal, in press, 26 page with 9 figures, some in color.
