Abstract
Recent studies with high-resolution cameras have extensively showed that clusters of galaxies are not as relaxed as we assumed. With its advent technology XMM-Newton allows us to obtain the temperature and metal abundance map in detail. In this study, we present our results related to six (A194, A1056, A1674, A1882, A2634, A2638) nearby (z < 0.14) clusters. These clusters have very poor X-ray atmosphere (ICM) and therefore it is very efficient to study individual galaxies and their evolution within ICM. Based on the temperature maps and morphology of bright member galaxies, we try to understand the perturbed galaxy emissions and dynamics of the clusters itself.
