Limits on Intergalactic Dust during Reionization
Imara N, Loeb A. Limits on Intergalactic Dust during Reionization. The Astrophysical Journal Letters. 2016;816 (1) :5. Publisher's VersionAbstract

In this Letter, we constrain the dust-to-gas ratio in the intergalactic medium (IGM) at high redshifts. We employ models for dust in the local universe to constrain the dust-to-gas ratio during the epoch of reionization at redshifts z ˜ 6-10. The observed level of reddening of high redshift galaxies implies that the IGM was enriched to an intergalactic dust-to-gas ratio of less than 3% of the Milky Way value by a redshift of z = 10.
