Abstract

The results of a new survey for distant galaxies identified on the basis of the damped Lyα absorption lines they produce in the spectra of high-redshift background QSOs are presented. These results are based on new, low-resolution spectroscopy of a sample of 57 QSOs, which are combined with similar low-resolution spectroscopy of 53 QSOs, to yield a total of 101 spectra of high-redshift QSOs which are suitable for identifying damped Lyα absorption lines. The spectra are analyzed to generate a complete sample of absorption features which, if the features are assumed to be Lyα lines, have rest-frame equivalent widths satisfying W ≥ 5 A. A total of 84 such damped Lyα absorption-line candidates are detected.
