The XMM Large Scale Structure Survey

We propose to map the distribution of matter over a 8x8 sq.deg. area out toredshifts of virgul12, using three complementary approaches: (1) Xray: galaxyclusters and QSOs;(2) Optical: galaxies and dark matter through a weak lensinganalysis; (3) SunyaevZel.dovich effect: diffuse extragalactic hot gas. Theproposed XMM survey at a sensitivity of virgul5E15 erg/s/cm2 in the 0.52 keV bandwill enable the construction of an homogeneous sample of some 900 galaxyclusters and, for the first time, the measurement of the cluster correlationfunction in 2 redshift bins: 0<z<0.5 & 0.5<z<1. The full data set will provideunprecedented insights into the initial fluctuation spectrum and the processesthat have modified these fluctuations since the recombination. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
