Aligned metal absorbers and the ultraviolet background at the end of reionization
(Oxford University Press, 2018)
We use observations of spatially-aligned C ii, C iv, Si ii, Si iv, and O i absorbers to probe the
slope and intensity of the ultraviolet background (UVB) at z ∼ 6. We accom- plish this by comparing
observations with ...
Testing galaxy formation simulations with damped Lyman-α abundance and metallicity evolution
(Oxford University Press, 2020)
We examine the properties of damped Lyman-α absorbers (DLAs) emerging from a single set of cosmological initial conditions in two state-of-the-art cosmological hydrodynamic simulations: SIMBA and TECHNICOLOR DAWN. The ...
The host haloes of O I absorbers in the reionization epoch
(Oxford University Press, 2013)
We use a radiation hydrodynamic simulation of the hydrogen reionization epoch to study
OI absorbers at z ∼ 6. The intergalactic medium (IGM) is reionized before it is enriched;
hence, OI absorption originates within dark ...
Physical properties of spectroscopically confirmed galaxies at Z ≥ 6. I. Basic characteristics of the rest-frame UV continuum and lyman-alpha emission
(American Astronomical Society, 2013)
We present deep HST near-IR and Spitzer mid-IR observations of a large sample of spectroscopically-
confirmed galaxies at z ≥ 6. The sample consists of 51 Ly-alpha emitters (LAEs) at z ≃ 5.7, 6.5, and 7.0,
and 16 Lyman-break ...
