The impact of helium reionization on the structure of the intergalactic medium
A. Meiksin, E. R. Tittley
We examine the impact of helium reionization on the structure of the intergalactic medium (IGM). We model the reionization using a radiative transfer (RT) code coupled to the combi…
He II Lyβ Gunn-Peterson Absorption: New HST Observations, and Theoretical Expectations
David Syphers, Scott F. Anderson, Wei Zheng +7
Observations of He II Lyα Gunn-Peterson troughs have proved to be a valuable probe of the epoch of helium reionization at z~3. Since this optical depth can become unmeasurably larg…
IGMtransmission: A Java GUI to model the effects of the Intergalactic Medium on the colours of high redshift galaxies
Christopher M. Harrison, Avery Meiksin, David Stock
IGMtransmission is a Java graphical user interface that implements Monte Carlo simulations to compute the corrections to colours of high-redshift galaxies due to intergalactic atte…
The micro-structure of the intergalactic medium I: the 21cm signature from dynamical minihaloes
Avery Meiksin
A unified description is provided for the 21cm signatures arising from minihaloes against a bright background radio source and against the Cosmic Microwave Background (CMB), within…
