Galaxy Clustering in the SDSS Redshift Survey

Idit Zehavi (University of Arizona)

The ongoing Sloan Digital Sky Survey (SDSS) is providing a wealth of information enabling extensive large-scale structure studies. I will present recent measurements of galaxy clustering with the SDSS redshift survey, using a sample of about 200,000 galaxies, concentrating on the two-point correlation function. The SDSS is particularly suitable for investigating the dependence of clustering on galaxy properties, and we focus on the dependence on color and on luminosity. We interpret the measurements using contemporary models of galaxy clustering, which help to elucidate the features of the observed correlation functions and provide insights on galaxy formation and the relation of galaxies and dark matter.
