| Description | CIZA J1358-4750 is one of the near-by early phase major merger clusters of galaxies. It has two distinct humps and a bright "bridge" region in between. With Suzaku temperature jump, XMM snap shot and Chandra images, we detected a Mach sim1.4 shock in the bridge, with a narrow 120. wide hump considered to be the post-shock region between the forward and reverse shocks. Here we propose a deep ( 90 virgulks) XMM-Newton observation to resolve the temperature structure in the post-shock region. Since the shock age is estimated to be as young as 70 virgulMyr, which is 1-3 of the electron Coulomb heating timescale tau_{c} , with the temperature distribution resolved in 24. slices, we are able to determine the actual heating timescale to be shorter than 1-8 tau_c . |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
