Intergalactic Dust Extinction in Hydrodynamic Cosmological Simulations

Abstract

Recently Ménard et al. (hereafter MSFR) detected a subtle but systematic change in the mean color of quasars as a function of their projected separation from foreground galaxies, extending to comoving separations of ∼ 10h−1Mpc, which they interpret as a signature of reddening by intergalactic dust. We present theoretical models of this remarkable… (More)
