| Abstract | We propose here XMM observations of Abell 1882; the first massive nearby clusterof galaxies observed by the SDSS. The region surrounding Abell 1882 is complexin the optical and X--ray wavelengths. In the optical, the main cluster core isextended with a bi-modal redshift distribution. However, the redshift histogramdoes not resemble typical merger scenarios. On the other hand, the peak X--rayemission is significantly offset from the galaxy concentration, indicative of amerging system. We will propose a detailed physical model for this system usinga combination of X--ray, optical data with new hydro/N--body simulations. Such amodel is essential for determining the roles of different physical mechanisms(e.g. turbulence, ram pressure, dissipation) on galaxy formation and evolution. |

| 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. |
