The XMM Large Scale Structure Survey

We propose to complete, by an additional 5 deg2, the XMMLSS Survey regionoverlying the Spitzer/SWIRE field. This field already has CFHTLS and Integralcoverage, and will encompass about 10 deg2. The resulting multiwavelengthmediumdepth survey, which complements XMM and Chandra deep surveys, willprovide a unique view of largescale structure over a wide range of redshift,and will show active galaxies in the full range of environments. The completecoverage by optical and IR surveys provides highquality photometric redshifts,so that cosmological results can quickly be extracted. In the spirit of a Legacysurvey, we will make the raw Xray data immediately public. Multibandcatalogues and images will also be made available on short time scales. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
