Our aim was to characterise the physical properties of the non-thermal component and its interaction with the cosmic microwave background. We performed spatially resolved spectroscopy and imaging using XMM-Newton data to model the thermal emission. Combining this with INTEGRAL ISGRI data, we modeled the 0.6-140 keV band total emission in the central 7 arcmin region. The models that best describe both PN and ISGRI data contain a power-law component with a photon index in a range 2.2-2.5.
