The abundances of metals in the intergalactic medium (IGM) can be used to constrain the amount of star formation at high redshift and the spectral shape of the ionizing background radiation. For both purposes, it is essential to measure the abundances in regions of low density, away from local sources of metals and ionizing photons. Here we report the first detection of O VI in the low-density IGM at high redshift. We perform a pixel-by-pixel search for O VI absorption in eight high-quality… Expand

Analysing carbon and oxygen absorption lines in quasar spectra allows us to probe the heavy-element abundances at a redshift of three within low-density regions of intergalactic gas and finds that the ratio of triply ionized carbon to neutral hydrogen is roughly constant over a wide range of densities.
