Dark matter and halo bispectrum in redshift space

In this talk we present an empirical model to describe the dark matter bispectrum monopole in redshift space at low redshifts. We extend this formalism to the biased tracers using a non-local bias model. We also show how the bispectrum, in combination with the power spectrum multipoles, can be used to extract cosmological information, such as the logarithmic growth factor and sigma8. We also show the applicability of this method to spectroscopic galaxy surveys, such as BOSS.
