Özet

In this work we study the A3560 cluster, which is located at the Shapley concentration core close to A3562 and A2558 (< 8 Mpc). Imaging analysis shows that the X-ray brightness is elliptical. The elongation is in the south-east to north-west direction which is the direction to A3558. This is interpreted as the mutual interaction of clusters in high density super-cluster regions of the sky. The ICM physical properties and distributions are studied by newly developed spectral mapping algorithms. The temperature and metal abundance maps show small scale variations. The coldest north-west peak has also the lowest metal abundance value which is a strong indicator of a recent sub-group merger with different physical properties.
