We investigate the dependence of strength galaxy clustering on intrinsic luminosity using Anglo-Australian two degree field redshift survey (2dFGRS). The 2dFGRS is over an order magnitude larger than previous surveys used to address this issue. measure projected two-point correlation function galaxies in a series volume-limited samples. free from any distortion pattern induced by peculiar motions and well described power law pair separation range . real space well-fitted length power-law slope amplitude increases slowly with absolute for fainter M*, but rises more strongly at higher luminosities. At low luminosities, our results agree measurements Southern Sky Redshift Survey 2 Benoist et al. However, we find weaker highest factor 4.0 between −22.5, most luminous are 3.0 times clustered L* galaxies. shows remarkably little variation samples spanning 20 luminosity. Our very good agreement predictions hierarchical formation models Benson
