Abstract


The enrichment of the intergalactic medium with heavy elements is aprocess that lies at the nexus of poorly-understood aspects ofphysical cosmology. We review current understanding of the processesthat may remove metals from galaxies, the basic predictions of thesemodels, the key observational constraints on enrichment, and howintergalactic enrichment may be used to test cosmological simulations.
