METAL ENRICHMENT OF THE INTERGALACTIC MEDIUM
Abstract:Recent observations show the presence of metals in low-density Lyα forest absorbers at high redshift (z∼3). It remains still far from being clearly understood what mechanisms spread metals over Mpc scales from the parent galaxies, whether metals are homogeneously distributed in the intergalactic medium (IGM), how metallicity of the IGM does evolve. These questions are brifely addressed in this review.
