Abstract | |||||||||||||
| . We present spectroscopic observations of galaxies lying within 1 0 of QSO J2233--606 in the Hubble Deep Field South (HDF-S). Several are found to be coincident in redshift with absorption-line systems seen in the HST J2233--606 spectrum. We detect a new z em = 1:336 QSO with I = 20:8 at a projected angular separation of 44.5 00 (or ae =200h \Gamma1 kpc; q 0 =0:5) from J2233--606. This QSO pair is an ideal target for QSO environment studies. Indeed, strong H I Lyff and Lyfi absorptions are seen at z abs =1:3367 in the J2233--606 spectrum. The bright spiral galaxy (J2233378--603324), projected at 4.7 00 from J2233-- 606, is at z = 0:570 (thus ae = 18h \Gamma1 kpc). Absorption is seen in the Lyman series at the same redshift but the weakness of the Lyman break implies N(H I) !10 17 cm \Gamma2 .
