| Abstract | CIZA J1358-4750 is one of the near-by early phase major merger clusters ofgalaxies. It has two distinct humps and a bright bridge region in between.With Suzaku temperature jump, XMM snap shot and Chandra images, we detected aMach $ sim1.4$ shock in the bridge, with a narrow $120$ wide hump consideredto be the post-shock region between the forward and reverse shocks. Here wepropose a deep ($90$~ks) XMM-Newton observation to resolve the temperaturestructure in the post-shock region. Since the shock age is estimated to be asyoung as $70$~Myr, which is $1/3$ of the electron Coulomb heating timescale $tau_{c}$, with the temperature distribution resolved in $24$ slices, we areable to determine the actual heating timescale to be shorter than $1/8$ $ tau_c$. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
