IGM metal enrichment through dust sputtering

We study the motion of dust grains into the Intergalactic Medium (IGM) around redshift z = 3, to test the hypothesis that grains can efficiently pollute the gas with metals through sputtering. We use the results available in the literature for radiation-driven dust ejection from galaxies as initial conditions, and follow the motion onward. Via this mechanism, grains are ejected into the IGM wit...

Metal enrichment of the intergalactic medium

I demonstrate by means of high resolution cosmological simulations, which include modelling of a two-phase interstellar medium, that the dominant mechanism for transporting heavy elements from the proto-galaxies into the IGM is the merger mechanism as discovered by Gnedin & Ostriker. Direct ejection of the interstellar gas by supernovae plays only a minor role in transporting metals into the IG...

Metal Enrichment of Ly alpha Clouds and Intergalactic Medium

We have examined the metal enrichment of the intergalactic medium (IGM) based on a galactic wind model. A galactic wind driven by supernovae brings metallic gas to the IGM but not so far beyond the gravitational potential. The expanding velocity of the outflow depends on the star formation timescale. Examining 3D calculation for the IGM in CDM model, we find that only 10 % region has metallicit...

Early Metal Enrichment of the Intergalactic Medium by Pregalactic Outflows

We assess supernova (SN)–driven pregalactic outflows as a mechanism for distributing the product of stellar nucleosynthesis over large cosmological volumes prior to the reionization epoch. SN ejecta will escape the grasp of halos with virial temperatures Tvir ∼ 10K (corresponding to masses M ∼ 10 h M⊙ at redshift z = 9 when they collapse from 2–σ fluctuations) if rapid cooling can take place, a...

Metal enrichment of the intergalactic medium in cosmological simulations

Observations have established that the diffuse intergalactic medium (IGM) at z ∼ 3 is enriched to ∼ 10 solar metallicity and that the hot gas in large clusters of galaxies (ICM) is enriched to 1/3−1/2Z⊙ at z = 0. Metals in the IGM may have been removed from galaxies (in which they presumably form) during dynamical encounters between galaxies, by ram-pressure stripping, by supernova-driven winds...
