Abstract

We present spectra of QSOs Q1343+266A, B, covering Lyβ to C IV emission at 2 Å resolution, and find further evidence that this system is not gravitationally lensed. We see, however, a large number of Lyα and some C IV absorption features common to both spectra. The frequency of C IV lines in common indicates that these absorbers have a radius close to the sight line separation, 39 h-1 kpc (q0 = 0.5), implying a spatial number density of these absorbers the same as current-day L > 0.3 L* galaxies. Furthermore, the velocity mismatch for C IV systems indicates absorber masses in the range 1011 M < M < 1012 M. These results confirm that typical galaxies cause QSO C IV-line absorption.
