Abstract

We built from all available long-term archival X-ray Observatory Chandra observations, using adaptive angular binning, hardness maps of X-rays from galaxy clusters Hydra A, Hercules A and MS 0735.6+7421 and analyzed them for signs of the presence of local non-thermal radiation. Our study showed that even collecting all the observations in the mosaic and the use of adaptive angular binning did not allow to distinguish non-thermal X-ray radiation from these objects. We have an upper limit for the number of non-thermal photons in that archival observations.

Keywords: galaxy clusters; active galaxy nucleus; X-ray radiation
