Testing Cosmological SZE-X-ray-Multi-Wavelength Galaxy Cluster Surveys

SunyaevZeldovich Effect (SZE) surveys have finally and successfully opened anew window to study the cosmic largescale structure in a more promising waythan previous methods. We have performed a coordinated SZE, Xray, andoptical/MIR survey to best understand the potential of this new survey techniqueand obtained the first exciting multiwavelength detections. Here we propose toextent the current small test area applying the new XMMNewton mosaic mode,which allows us to adapt our survey optimally to the depth of the SZE surveysallowing for about 100 cluster detections with XMM. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
