Constraining the Metallicity of the Low Density Lyman-Alpha Forest Using OVI Absorption

Abstract

We present a systematic search for OVI(1032Å,1037Å) absorption in a Keck HIRES spectrum of the z = 3.62 quasar Q1422+231, with the goal of constraining the metallicity and ionization state of the low density intergalactic medium (IGM). Comparison of CIV absorption measurements to models of the Lyα forest based on cosmological simulations shows that… (More)
