Abstract
For the purpose of studying the properties of heavy elements associated with the Lyman α forest, we observed the gravitational lens Q1422+2309. We used the HIRES instrument on the W.M. Keck telescope to obtain a high resolution, very high signal-to-noise spectrum of this z = 3.63 quasar; the spectrum covers wavelengths from below Lyman β up to the C IV emission line. Consistent with previous estimates, we find that a moderate fraction of the Ly α forest clouds have been enriched with heavy elements at a level significantly below solar abundance. However, unlike the fairly uniform distribution of Ly α forest lines, we show that the C IV absorption lines are clustered on large velocity scales.
