Effects of the local bias on the reconstruction of large-scale structure

Effects of biasing on the reconstruction of the large-scale matter structur e from the distribution of galaxies are studied on the assumption of the lo cal bias mechanism. We derive a simple analytic formula predicting the accu racy of each reconstructed Fourier mode. It is shown that in future redshif t surveys such as the Sloan Digital Sky Survey, the noise from the local bi as could be comparable with (or even greater than) the shot noise due to th e discreteness of observed galaxies.
