Observations of metals in the $z\approx 3.5$ intergalactic medium and comparison to the EAGLE simulations

Monica L. Turner, Joop Schaye, Robert A. Crain +2

We study the $z\approx 3.5$ intergalactic medium (IGM) by comparing new, high-quality absorption spectra of eight QSOs with $⟨z_{\mathrm{QSO}}⟩=3.75$, to virtual observatio…
