The clustering properties of the first galaxies

Stiavelli & Trenti, http://arxiv.org/abs/0911.3368

These authors suggest the idea that the very first galaxies that are most highly clustered may not be not be as primordial in chemical composition as naively expected. This is because the high clustering implies rapid enrichment. Metal-free galaxies may therefore best be searched for in less-custered underdense regions. Hence, primordial galaxies may be second (in terms of chronological order).
