Spatially resolved spectroscopy of the cluster of galaxies A 2199
Abstract
The X-ray spectrum of the bright cD cluster of galaxies A 2199 is studied using all instruments of BeppoSAX. Spatially resolved spectroscopy with the MECS instrument shows the presence of spectral hardening in the outer parts of the cluster. The presence of a hard tail is also confirmed by the simultaneous PDS observations. Our analysis shows that the hard component cannot be due to a population of point sources like AGN but corresponds to a diffuse non-thermal component. We also discuss the presence of resonance scattering in this cluster.
