XMM-Newton and INTEGRAL analysis of the Ophiuchus cluster of galaxies

Understand

We investigated the non-thermal hard X-ray emission in the Ophiuchus cluster of galaxies.

• 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.
