We present a detailed Chandra, XMM-Newton, VLA and HST analysis of one of thestrongest cool core clusters known, RX J1532.9+3021 (z=0.3613). Using new, deep90 ks Chandra observations, we confirm the presence of a western X-ray cavityor bubble, and report on a newly discovered eastern X-ray cavity. The totalmechanical power associated with these AGN-driven outflows is (22+/-9)*10^44erg/s, and is sufficient to offset the cooling, indicating that AGN feedbackstill provides a viable solution to the cooling flow problem even in thestrongest cool core clusters. Based on the distribution of the opticalfilaments, as well as a jet-like structure seen in the 325 MHz VLA radio map,we suggest that the cluster harbours older outflows along the north to southdirection. The jet of the central AGN is therefore either precessing orsloshing-induced motions have caused the outflows to change directions. Thereare also hints of an X-ray depression to the north aligned with the 325 MHzjet-like structure, which might represent the highest redshift ghost cavitydiscovered to date. We further find evidence of a cold front (r=65kpc) thatcoincides with the outermost edge of the western X-ray cavity and the edge ofthe radio mini-halo. The common location of the cold front with the edge of theradio mini-halo supports the idea that the latter originates from electronsbeing reaccelerated due to sloshing induced turbulence. Alternatively, itscoexistence with the edge of the X-ray cavity may be due to cool gas beingdragged out by the outburst. We confirm that the central AGN is highlysub-Eddington and conclude that a >10^10M_Sun or a rapidly spinning black holeis favoured to explain both the radiative-inefficiency of the AGN and thepowerful X-ray cavities.
