A test for the origin of quasar redshifts.
POPOWSKI P. and WEINZIERL W.
Abstract (from CDS):
We give the predictions for the maximum possible proper motions of a quasar for the cosmological and local scenarios of the origin of their redshifts. We apply these theoretical results to the Bukhmastova catalogue, which contains more than 8000 close quasi-stellar object-galaxy associations. In the standard interpretation of quasar redshifts, their typical proper motions are a fraction of µas, and beyond the reach of planned astrometric missions such as GAIA and SIM. On the other hand, the quasars ejected from local active galactic nuclei at velocities close to the speed of light would have proper motions 5-6 orders of magnitude larger, which would easily be measurable with future astrometric missions, or even in some cases with HST, VLT and Keck telescope. The distributions of proper motions for the cosmological and local scenarios are very well separated. Moreover, the division corresponds nicely to the expected accuracy from GAIA and SIM.
