Dynamics of a sample of 14 clusters of galaxies using X-ray and / or Radio observations

I will present detailed analysis of the environments of 14 clusters of galaxies using their available archival Chandra and/or XMM-Newton X-ray observations. The clusters are selected from the combined samples of Flin and Krywult (2008) and Ramella et al. (2007), on the basis of the presence of optical substructures in them. Two of the clusters viz., A3395 and A3532, have also been studied at various wavelengths in the radio and the BCGs of both these clusters are seen to host Wide Angle Tailed (WAT) radio sources. The exposure corrected and point source removed X-ray images of most of the clusters of the sample show anisotropic X-ray morphologies. X-ray substructures and multiple nuclei are also seen in the central parts of many of these clusters. One of the clusters, A193, shows a triple nucleus at its centre in the Chandra image, previously seen only in the K-band observations with the UKIRT and in the I-band observations with the Hubble Space Telescope (HST) (Seigar et al. 2003). To study the spatial  variations of the thermodynamic quantities, we have also made azimuthally averaged profiles and 2-D maps of temperature, electron number density, entropy and pressure for all the clusters by using results obtained from the X-ray spectral analyses.
