CIZA J1358.9-4750 is a nearby (z = 0.074) pair of clusters of galaxies located close to the Galactic plane. It consists of two X-Ray extended humps at north-west and south-east separated by 14 arcmin (~ 1.2 Mpc), and an X-Ray bright bridge-like structure in between. With Suzaku, the south-east hump was shown to have a temperature of 5.6 keV and the north-west one 4.6 keV. Neither humps exhibit significant central cool component. The bridge region has a temperature higher than 9 keV at the…
