Scientific paper

It is shown here that a systematic luminosity segregation effect in the clustering of galaxies is expected and provides an unambiguous test of the biased galaxy formation theory. How the clustering of galaxies correlates with their luminosity is examined in detail using different biased models and numerical simulations. It is found that a strong effect is expected of luminosities larger than L(asterisk), the characteristic luminosity of galaxies, and that the amplitude of the predicted effect at these luminosities agrees with observations. At luminosities fainter than L(asterisk), however, strong limits are put on this segregation effect. These limits are incompatible with any biased cold dark matter theory in which the bias parameter for bright galaxies is greater than 1.5 on large scales.
