Metal enrichment of the intergalactic medium at z=3 by galactic winds
galactic winds intergalactic medium
2014/12/26
Studies of quasar absorption lines reveal that the low-density intergalactic medium (IGM) at z ~ 3 is enriched to between 10-3 and 10-2 solar metallicity. This enrichment may have occurred in an early...
This paper discusses a semi-numerical method of investigating
the enrichment of the intergalactic medium by galactic winds. We
find that most galaxies at z ～ > 3 should be driving winds, and that (i...
