dc.descriptionWe report on results from the Durham/UKST Galaxy Redshift Survey where we have found large scale ``cellular'' features in the galaxy distribution. These have spatial 2-point correlation function power significantly in excess of the predictions of the standard cold dark matter cosmological model$^{1}$, supporting the previous observational results from the APM survey$^{2,3}$. At smaller scales, the 1-D pairwise galaxy velocity dispersion is measured to be $\bf 387^{+96}_{-62}$ kms$^{-1}$ which is also inconsistent with the prediction of the standard cold dark matter model$^{1}$. Finally, the survey has produced the most significant detection yet of large scale redshift space distortions due to dynamical infall of galaxies$^{4}$. An estimate of $\bf Ω^{0.6}/b = 0.55 \pm 0.12$ is obtained which is consistent either with a low density Universe or a critical density Universe where galaxies are biased tracers of the mass.
