Magnetic Field Structure in the Radio Lobes of Centaurus B

An observation is proposed for a bright radio galaxy Centarus B.ASCA detected an extended nonthermal Xray emission from its radiolobes, which is produced via inverseComptonization (IC) of the cosmic microwave photons. A 30 ksec exposure onto the target with XMM will provide a spatial distribution of the IC Xrays with a much higher accuracy than was achieved with ASCA. By comparing the IC Xray emission with the synchrotron radio emission, spatial structure of magnetic fields and distributions of the relativistic electrons will be derived. This will provide valuable informationas to the physical condition of lobes of the active galaxy in general. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
