Abstract

We study the contents of an apparent void in the distribution of Lya emitting galaxies at redshift 2.38. We show that this void is not empty, but contains a damped Lya absorption-line system, seen in absorption against background QSO 2138–4427. Imaging does not reveal any galaxy associated with this absorption-line system, but it contains metals (Fe/H ~ — 1.3), and its large velocity range (~ 180 km s^-1) implies a significant mass.
