Powering reionization: assessing the galaxy ionizing photon budget at z < 10
We present a new analysis of the ionizing emissivity ( $\dot{N}_{\rm {ion}}$ , s−1 Mpc−3) for galaxies during the epoch of reionization and their potential for completing and maintaining reionization. We use extensive spectral energy distribution modelling – incorporating two plausible mechanisms fo...

| Zusammenfassung: | We present a new analysis of the ionizing emissivity (
$\dot{N}_{\rm {ion}}$
, s−1 Mpc−3) for galaxies during the epoch of reionization and their potential for completing and maintaining reionization. We use extensive spectral energy distribution modelling – incorporating two plausible mechanisms for the escape of Lyman continuum photon – to explore the range and evolution of ionizing efficiencies consistent with new results on galaxy colours (β) during this epoch. We estimate
