The Kaiser-Rocket effect: three decades and counting [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 Abstract 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 ...
