Beyond the plane-parallel and Newtonian approach: Wide-angle redshift
distortions and convergence in general relativity    [PDF]

We extend previous analyses of wide-angle correlations in the galaxy power spectrum in redshift space to include the general relativistic effects. These general relativistic corrections to the standard approach become important on large scales and at high redshifts - and they lead to new terms in the wide-angle correlations. We show these can lead to corrections of nearly 10% over the usual Newtonian approximation.
