The Lyman-alpha forest opacity and the metagalactic hydrogen ionization rate at z~2-4 (2005)
Journal Article
S. Bolton, J., G. Haehnelt, M., Viel, M., & Springel, V. (2005). The Lyman-alpha forest opacity and the metagalactic hydrogen ionization rate at z~2-4. Monthly Notices of the Royal Astronomical Society, 357(4), 1178–1188. https://doi.org/10.1111/j.1365-2966.2005.08704.x

Estimates of the metagalactic hydrogen ionization rate from the Lyman-alpha forest opacity in QSO absorption spectra depend on the complex density distribution of neutral hydrogen along the line-of-sight. We use a large suite of high resolution hydro... Read More about The Lyman-alpha forest opacity and the metagalactic hydrogen ionization rate at z~2-4.

Radiative transfer through the intergalactic medium (2004)
Journal Article
Bolton, J., Meiksin, A., & White, M. (2004). Radiative transfer through the intergalactic medium. Monthly Notices of the Royal Astronomical Society, 348(3), L43-L48. https://doi.org/10.1111/j.1365-2966.2004.07567.x

We use a probabilistic method to compute the propagation of an ionization front corresponding to the reionization of the intergalactic medium in a Λ-cold dark matter (ΛCDM) cosmology, including both hydrogen and helium. The effects of radiative trans... Read More about Radiative transfer through the intergalactic medium.

Electric field strengths and ion trajectories in sharp-edge field ionization sources (1970)
Journal Article
Brailsford, D. F. (1970). Electric field strengths and ion trajectories in sharp-edge field ionization sources. Journal of Physics D: Applied Physics, 3,

On the presumption that a sharp edge may be represented by a hyperbola, a conformal transformation method is used to derive electric field equations for a sharp edge suspended above a flat plate. A further transformation is then introduced to give el... Read More about Electric field strengths and ion trajectories in sharp-edge field ionization sources.
