The Kaiser-Rocket effect: three decades and counting
  The peculiar motion of the observer, if not accurately accounted for, is
bound to induce a well-defined clustering signal in the distribution of
galaxies. This signal is related to the Kaiser rocket effect. Here we examine
the amplitude and form of this effect, both analytically and numerically, and
discuss possible implications for the analysis and interpretation of
forthcoming cosmological surveys. For an idealistic cosmic variance dominated
full-sky survey with a Gaussian selection function peaked at $z\sim 1.5$ it is
a $> 5\sigma$ effect and it can in principle bias very significantly the
inference of cosmological parameters, especially for primordial
non-Gaussianity. For forthcoming surveys, with realistic masks and selection
functions, the Kaiser rocket is not a significant concern for cosmological
parameter inference. However, it is a systematic effect whose origin, nature
and imprint on galaxy maps are well known and thus should be subtracted or
mitigated. We present several approaches to do so.
