The three-point correlation function (3PCF) describes the probability of finding three objects in a particular triangle configuration, compared to a random sample. This is a complementary measure of clustering in the Large Scale Structure which allow us to gain new information on galaxy biasing, galaxy formation, as well as cosmological parameters.
We will present results of 3PCF measurements from the SDSS Luminous Red Galaxy Sample, which allow us to determine non-linear biasing and help in constraining cosmological parameters.
We also will show preliminary results on the luminosity and color dependence of the DR7 SDSS Main Galaxy Sample 3PCF, and comparing to simulated mock catalogs, explore how we can extract information on halo occupation and environmental effects in galaxy formation.
