Kaiser Rocket effect becomes significant at large scales and high redshifts.

New contributions to wide-angle correlations due to the Kaiser Rocket effect.

Implications for future large-volume galaxy surveys.

Abstract

We study wide-angle correlations in the galaxy power spectrum in redshift space, including all general relativistic effects and the Kaiser Rocket effect in general relativity. We find that the Kaiser Rocket effect becomes important on large scales and at high redshifts, and leads to new contributions in wide-angle correlations. We believe this effect might be very important for future large volume surveys.
