CLUSTERING AND LARGE-SCALE STRUCTURE WITH THE SLOAN DIGITAL SKY SURVEY

The Sloan Digital Sky Survey (SDSS) will provide a complete imaging an d spectroscopic survey of the high-latitude northern sky. The 2D surve y will image the sky in five colors and will contain nearly 5X10(7) ga laxies to g similar to 23 mag. The spectroscopic survey will obtain sp ectra of the brightest 10(6) galaxies, 10(5) quasars, and 10(3.5) rich clusters of-galaxies (to g similar to 18.3-19.3 mag, respectively). I summarize some of the science opportunities that will be made possibl e by this survey for studying the clustering and large-scale structure of the Universe. The survey will identify a complete sample of severa l thousand rich clusters of galaxies, both in 2D and 3D-the largest au tomated sample yet available. The extensive cluster sample can be used to determine critical clustering properties such as the luminosity fu nction, velocity function, and mass function of clusters of galaxies ( a critical test for cosmological models), detailed cluster dynamics an d Omega(dyn), the cluster correlation function and its dependence on r ichness, cluster evolution, superclustering and voids to the largest s cales yet observed, the motions of clusters and their large-scale pecu liar velocity field, as well as detailed correlations between X-ray an d optical properties of-clusters, the density-morphology relation, and cluster-quasar associations. The large redshift survey, reaching to a depth of greater than or similar to 600h(-1) Mpc, will accurately map the largest scales yet observed, determine the power-spectrum and cor relation function on these large scales for different-type galaxies, a nd study the clustering of quasars to high redshifts (z greater than o r similar to 4). The implications of the survey for cosmological model s, the dark matter, and Omega are also discussed.
