Query: Study on the mapping of halo clustering from real space to redshift
  space   The mapping of galaxy clustering from real space to redshift space introduces
the anisotropic property to the measured galaxy density power spectrum in
redshift space, known as the redshift space distortion (RSD) effect. The
mapping formula is intrinsically non-linear, which is complicated by the higher
order polynomials due to indefinite orders of cross correlations between
density and velocity fields, and the Finger--of--God (FoG) effect due to the
randomness of the galaxy peculiar velocity field. In previous works, we have
verified the robustness of advanced TNS mapping formula in our hybrid RSD model
in dark matter case, where the halo bias models are not taken into account for
the halo mapping formula in redshift space. Using 100 realizations of halo
catalogs in N-body simulations, we find that our halo RSD model with the known
halo bias model and the effective FoG function accurately predicts the halo
power spectrum measurements, within 1$\sim$2% accuracy up to $k\sim 0.2h$/Mpc,
depending on different halo masses and redshifts.
