Abstract

The observed clustering of Lyman-α lines is reviewed and compared with the clustering of CIV systems. We argue that a continuity of properties exists between Lyman-α and metal systems and show that the small-scale clustering of the absorbers is consistent with a scenario of gravitationally induced correlations. At large scales statistically significant over and under-densities (including voids) are found on scales of tens of Mpc.
