Scientific paper

The authors present medium-resolution observations of the absorption-line spectrum of the quasar Tol 1038-27 (z = 2.32) and point out its remarkable similarity to that of the nearby quasar Tol 1037-27 (z = 2.18). Both objects display a broad C IV system centered near z = 2.08 in addition to three neighboring C IV systems that coincide in redshift in the two quasars to within 2000 km s-1. At an angular separation of 17arcmin.9, the projected distance between the lines of sight to the two objects is of order ≡4 Mpc. The absorption therefore may be caused by a massive intervening supercluster.
