I am interested in whether it is necessary to account for the effects of the Hubble Redshift in determining the rotation velocities of galaxies exhibiting keplerian motion and, in particular, whether the associated spatial expansion of the Universe is known to result in spectral shifts that produce an observed asymmetry in the apparent LOS velocity between material in these systems that is moving toward and material that is moving away from the observer. I would also appreciate any references in the literature where this specific subject is discussed.(adsbygoogle = window.adsbygoogle || []).push({});
