| Abstract: | In this paper, we present a redshift space reconstruction scheme which
is analogous to and extends the Perturbative Least Action (PLA) method
described by Goldberg & Spergel (2000). We first show that this scheme is
effective in reconstructing even nonlinear observations. We then suggest that by
varying the cosmology to minimize the quadrupole moment of a reconstructed
density field, it may be possible to lower the errorbars on the redshift distortion
parameter, β as well as to break the degeneracy between the linear bias
parameter, b, and UM. Finally, we discuss how PLA might be applied to realistic
redshift surveys. |
