Damped Systems Associated with a Galaxy Cluster at Z=2.38
We have found a unique cluster of three damped Lyman-alpha systems at redshift 2.38 seen in absorption against three background QSOs. One of the damped systems lies in the centre of a rich galaxy cluster - indeed it lies less than 150 kpc from a pair of giant elliptical galaxies. Despite this dense environment the gas is cold and has a metallicity of only -2.7 dex. Another damped system lies roughly 10 co-moving Mpc away in the middle of a void. Despite this low density location it has a much...[Show more]
