We use the observed abundance and clustering of galaxies from the 2dF Galaxy Redshift Survey to determine the matter density Ωm and the linear amplitude of mass fluctuations σ8. We use a method based on the conditional luminosity function, which allows straightforward computation of the luminosity dependent bias, b, of galaxies with respect to the matter… CONTINUE READING
