Radial and transverse velocities of nearby galaxies.

Abstract (from CDS):

Analysis of the peculiar velocities of the galaxies should take account of the uncertainties in both redshifts and distances. We show how this can be done by a numerical application of the action principle. The method is applied to an improved catalog of the galaxies and tight systems of galaxies within 4h–175 Mpc, supplemented with a coarser sample of the major concentrations at 4h–175 Mpc to 20h–175 Mpc distance. Inclusion of this outer zone improves the fit of the mass tracers in the inner zone to their measured redshifts and distances, yielding best fits with reduced χ2 in redshift and distance in the range 1.5-2. These solutions are based on the assumption that the galaxies in and near the Local Group trace the mass, and a powerful test would be provided by observations of proper motions of the nearby galaxies. Predicted transverse galactocentric velocities of some of the nearby galaxies are confined to rather narrow ranges of values, and are on the order of 100 km.s–1, large enough to be detected and tested by the proposed SIM and GAIA satellite missions.
