Fig. 5


Rest-frame UV spectra obtained with FORS2 for the ten confirmed cluster members of the galaxy structure at z = 2.02. Identification numbers from the B-band catalogue and redshift (followed by “(B)” if it is a low quality redshift) are indicated at the upper left corner of each spectrum. The spectra were rebinned by a factor of two. Sky lines are indicated by gray vertical lines. Prominent emission and absorption lines expected in this spectral range are shown by the vertical dotted lines: Lyαλ1216 (1), SiII λ1260 (2), OI/SiII (3; OS, λ1303), CII λ1334 (4), SiIV λ1402 (5), SiII λ1526 (6), CIV λ1550 (7), FeII λ1608 (8), HeII λ1640 (9), AlII λ1670 (10), SiII λ1808 (11), AlIII λ1854 (12) and CIII] λ1909 (13). The absorption/emission lines detected in each individual spectrum are marked by the red ticks and also listed in Table A.1.
