Imaging a Cluster of Galaxies at Redshift 2.38

Francis, Paul


We have discovered 8 galaxies at redshift 2.38, forming what we believe to be a rich galaxy cluster in the early stages of formation. A sub-set of 4 galaxies within the cluster form a very compact {< 100 kpc} galaxy group and may be merging to form a giant elliptical galaxy. This proto- elliptical is embedded in an extended, Ly-Alpha emitting, lumpy cloud of gas and dust, which is probably responsible for a complex of Lyman-limit absorption systems in the spectrum of a background QSO.
