Query: Application of the iterative reconstruction to simulated galaxy fields   We apply an iterative reconstruction method to galaxy mocks in redshift space
obtained from $N$-body simulations. Comparing the two-point correlation
functions for the reconstructed density field, we find that although the
performance is limited by shot noise and galaxy bias compared to the matter
field, the iterative method can still reconstruct the initial linear density
field from the galaxy field better than the standard method both in real and in
redshift space. Furthermore, the iterative method is able to reconstruct both
the monopole and quadrupole more precisely, unlike the standard method. We see
that as the number density of galaxies gets smaller, the performance of
reconstruction gets worse due to the sparseness. However, the precision in the
determination of bias ($\sim20\%$) hardly impacts on the reconstruction
processes.
