Scientific paper

We propose a 100ks ACIS-S observation of the radio-galaxy/ICM interaction in Abell 4059. Our previous (cycle-1) observation showed this interaction to be dramatic and complex, with large "ghost" cavities resulting from a previous powerful outburst of the radio-galaxy PKS2354-35. We also discovered clear radial gradients in ICM temperature and metallicity. The new observations will double the signal-to-noise and allow us to take our investigation to the next level of sophistication. By making detailed temperature and metallicity maps, we will search for signs of radio galaxy induced heating and/or mixing of the ICM. We will also constrain models for the curious "south-west ridge" first noted by Huang & Sarazin.
