A Multiwavelength Study of the Cosmic Web

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 Xray wavelengths. In the optical, the main cluster core isextended with a bimodal redshift distribution. However, the redshift histogramdoes not resemble typical merger scenarios. On the other hand, the peak Xrayemission is significantly offset from the galaxy concentration, indicative of amerging system. We will propose a detailed physical model for this system usinga combination of Xray, optical data with new hydro/Nbody simulations. Such amodel is essential for determining the roles of different physical mechanisms(e.g. turbulence, ram pressure, dissipation) on galaxy formation and evolution. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
