Exploring the thermal state of the low-density intergalactic medium at z = 3 with an ultra-high signal-to-noise QSO spectrum (2016)
Journal Article

Exploring the thermal state of the low-density intergalactic medium at z = 3 with an ultra-high signal-to-noise QSO spectrum. Monthly Notices of the Royal Astronomical Society, 466(3), 2690-2709. https://doi.org/10.1093/mnras/stw2917

At low densities, the standard ionization history of the intergalactic medium (IGM) predicts a decreasing temperature of the IGM with decreasing density once hydrogen (and helium) reionization is complete. Heating the high-redshift, low-density IGM a... Read More about Exploring the thermal state of the low-density intergalactic medium at z = 3 with an ultra-high signal-to-noise QSO spectrum.

The Sherwood simulation suite: overview and data comparisons with the Lyman-α forest at redshifts 2≤z≤5 (2016)
Journal Article
Bolton, J. S., Puchwein, E., Sijacki, D., Haehnelt, M. G., Kim, T., Meiksin, A., …Viel, M. (2017). The Sherwood simulation suite: overview and data comparisons with the Lyman-α forest at redshifts 2≤z≤5. Monthly Notices of the Royal Astronomical Society, 464(1), 897-914. https://doi.org/10.1093/mnras/stw2397

We introduce a new set of large-scale, high-resolution hydrodynamical simulations of the intergalactic medium: the Sherwood simulation suite. These are performed in volumes of 103–1603h−3 comoving Mpc3, span almost four orders of magnitude in mass re...

Inferring the IGM thermal history during reionization with the Lyman α forest power spectrum at redshiftz≃ 5 (2016)
Journal Article
Nasir, F., Bolton, J. S., & Becker, G. D. (2016). Inferring the IGM thermal history during reionization with the Lyman α forest power spectrum at redshiftz≃ 5. Monthly Notices of the Royal Astronomical Society, 463(3), 2335-2347. https://doi.org/10.1093/mnras/stw2147

We use cosmological hydrodynamical simulations to assess the feasibility of constraining the thermal history of the intergalactic medium during reionisation with the Lyα forest at z ≃ 5. The integrated thermal history has a measureable impact on the... Read More about Inferring the IGM thermal history during reionization with the Lyman α forest power spectrum at redshiftz≃ 5.

Testing the effect of galactic feedback on the IGM at z∼ 6 with metal-line absorbers (2016)
Journal Article
Keating, L. C., Puchwein, E., Haehnelt, M. G., Bird, S., & Bolton, J. S. (2016). Testing the effect of galactic feedback on the IGM at z∼ 6 with metal-line absorbers. Monthly Notices of the Royal Astronomical Society, 461(1), 606-626. https://doi.org/10.1093/mnras/stw1306

We present models of low- and high-ionization metal-line absorbers (O i, C ii, C iv and Mg ii) during the end of the reionization epoch, at z ∼ 6. Using four cosmological hydrodynamical simulations with different feedback schemes (including the Illus...
