Abstract
The apparent Local Group motion inferred from infrared observations of an all-sky sample of spiral galaxies is interpreted in terms of a large-scale streaming motion for these galaxies on a scale of 50 h -1 Mpc. If this streaming is induced by large-scale density fluctuations, the fluctuations required are compatible with the observed distribution of luminous matter, but only in a closed universe. In the context of current speculation regarding non-baryonic particle species which may dominate the mass of the universe, this result seems to be inconsistent with cold dark matter models.
