The escape fraction of ionizing photons from high redshift galaxies (2008)
Srbinovsky, Jhan, Wyithe, Stuart
The fraction of ionizing photons which escape their host galaxy and so are able to ionize hydrogen in the inter-galactic medium (IGM) is a critical parameter in studies of the reionization era and...
Constraining the Quasar Contribution to the Reionisation of Cosmic Hydrogen (2006)
Srbinovsky, Jhan, Wyithe, Stuart
Absorption spectra of high redshift quasars suggest that the reionisation of cosmic hydrogen was complete near z~6. The dominant sources of ionising photons responsible for this reionisation are...
