- W2149078886 abstract "The observed high covering fractions of neutral hydrogen (|${rm H,small {rm I}}$|) with column densities above ∼1017 cm−2 around Lyman-Break Galaxies (LBGs) and bright quasars at redshifts z ∼ 2–3 has been identified as a challenge for simulations of galaxy formation. We use the Evolution and Assembly of Galaxies and their Environment (EAGLE) cosmological, hydrodynamical simulation, which has been shown to reproduce a wide range of galaxy properties and for which the subgrid feedback was calibrated without considering gas properties, to study the distribution of |${rm H,small {rm I}}$| around high-redshift galaxies. We predict the covering fractions of strong |${rm H,small {rm I}}$| absorbers (|${N_{rm H,small {I}}}gtrsim 10^{17} ,{rm cm^{-2}}$|) inside haloes to increase rapidly with redshift but to depend only weakly on halo mass. For massive (M200 ≳ 1012M⊙) haloes, the covering fraction profiles are nearly scale-invariant and we provide fitting functions that reproduce the simulation results. While efficient feedback is required to increase the |${rm H,small {rm I}}$| covering fractions to the high observed values, the distribution of strong absorbers in and around haloes of a fixed mass is insensitive to factor of 2 variations in the strength of the stellar feedback. In contrast, at fixed stellar mass the predicted |${rm H,small {rm I}}$| distribution is highly sensitive to the feedback efficiency. The fiducial EAGLE simulation reproduces both the observed global column density distribution function of |${rm H,small {rm I}}$| and the observed radial covering fraction profiles of strong |${rm H,small {rm I}}$| absorbers around LBGs and bright quasars." @default.
