| Description | We propose a deep XMM observation of the 1e14 Msun cluster XLSSC 105 at z=0.43, which exhibits clear merging signatures in existing multi-wavelength data. The two peaks revealed by high-resolution SZ data do not have obvious counterparts in the existing shallow XMM data, which implies that this system is a high-velocity head-on merger along the plane of the sky. The two SZ peaks likely coincide with high-temperature (>virgul20 keV) shock-heated regions. We propose a deep (175 ks) XMM observation of this system to measure the temperature of the gas in the shocked regions and constrain the geometry of the merger, together with a joint 70ks Chandra high-resolution observation to detect the density jumps. |

| 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. |
