Galaxy Clustering and Dark Matter Halos
Idit Zehavi (CWRU)
The recently-completed Sloan Digital Sky Survey (SDSS) has been immensely
useful for studies of the large-scale structure of the universe. I will
present new measurements of galaxy clustering from the full SDSS redshift
survey, concentrating on the projected 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 luminosity.
We interpret the measurements using contemporary models of galaxy clustering,
which elucidate the features of the observed correlation functions and
constrain the relation between galaxies and dark matter halos, providing
insight on galaxy formation and evolution.
