Zusammenfassung:A new class of cosmological tests is proposed which examines the dependence on redshift z of the dispersion in peculiar velocities, virial mass, and mass-luminosity ratios of galactic clusters. Data on galactic clusters with redshifts up to z ≈ 2 are accessible to modern instruments in the visible and x-ray ranges. Clusters of galaxies are less susceptible to evolutionary effects than other objects at large z , so that the proposed tests offer promise for analysis of cosmological models.
