Lyman-alpha emitters gone missing: evidence for late reionization?
Tirthankar Roy Choudhury, Ewald Puchwein, Martin G. Haehnelt +1
We combine high resolution hydrodynamical simulations with an intermediate resolution, dark matter only simulation and an analytical model for the growth of ionized regions to esti…
Gas around galaxy haloes: methodology comparisons using hydrodynamical simulations of the intergalactic medium
Avery Meiksin, James S. Bolton, Eric R. Tittley
We perform cosmological simulations of the intergalactic medium (IGM) at redshift z ~ 3 using the numerical gravity-hydrodynamics codes GADGET-3 and Enzo for the purpose of modelli…
The photoheating of the intergalactic medium in synthesis models of the UV background
Ewald Puchwein, James S. Bolton, Martin G. Haehnelt +3
We compare cosmological hydrodynamical simulations combined with the homogeneous metagalactic UV background (UVB) of Haardt & Madau (2012) (HM2012) to observations of the Lyman-alp…
Heating and Ionization of the Primordial Intergalactic Medium by High Mass X-ray Binaries
Gillian Knevitt, Graham Wynn, Chris Power +1
We investigate the influence of High Mass X-ray Binaries on their high redshift environments. Using a one-dimensional radiative transfer code, we predict the ionization and tempera…
Evidence of patchy hydrogen reionization from an extreme Ly trough below redshift six
George D. Becker, James S. Bolton, Piero Madau +3
We report the discovery of an extremely long (110 Mpc/) and dark () Ly trough extending down to towards the $z_{\rm em} \simeq 6.0…
IGM Constraints from the SDSS-III/BOSS DR9 Ly-alpha Forest Flux Probability Distribution Function
Khee-Gan Lee, Joseph P. Hennawi, David N. Spergel +13
The Ly forest transmission probability distribution function (PDF) is an established probe of the intergalactic medium (IGM) astrophysics, especially the temperature-density rel…
