Hubble Flow

AbstractDeviations from the Hubble flow directly probe of the underlying total mass distribution, assuming the gravitational instability picture. We discuss the origin of motion of the Local Group with respect to the Cosmic Background Radiation and review the peculiar velocity field deduced from distances to hundreds of elliptical and spiral galaxies, including new results for the Shapley Supercluster. Bulk-flow solutions which are free of Malmquistbias are presented, indicating coherence length larger than that expected from the optical and IRAS dipoles or from Cold Dark Matter models.

I review the assumptions and observations that motivate the concept of the extragalactic cosmic background radiation, and the issues of energy accounts and star formation history as a function of galaxy morphological type that figure in the interpretation of the measurements of the extragalactic infrared background.
