Scientific paper

A short (6 ks) ROSAT HRI image has revealed striking substructure within the intracluster medium of the galaxy cluster A4059. Two cavities within the X-ray emission are very apparent with the same position angle as the axis of the central radio source, PKS2354-35. By analogy with the Perseus cluster and Cygnus-A, these cavities are likely to be regions of the ICM that have been evacuated by the expanding radio-lobes. We propose 40ks AXAF ACIS observations of this system primarily to study the morphology and spectrum of these cavities and the bounding shocks. The physical nature of the X-ray bar seen in the ROSAT images will also be determined. Furthermore, we can form detailed temperature and absorption maps for this cluster thereby allowing details of the cooling flow to be explored.
