The impact of faint AGN discovered by JWST on reionization
Shikhar Asthana, Martin G. Haehnelt, Girish Kulkarni +4
The relative contribution of emission from stellar sources and accretion onto supermassive black holes to reionization has been brought into focus again by the apparent high abunda…

Chronicling the reionization history at with emergent quasar damping wings
Dominika ÄurovÄÃková, Anna-Christina Eilers, Huanqing Chen +6
The spectra of high-redshift () quasars contain valuable information on the progression of the Epoch of Reionization (EoR). At redshifts , the observed Lyman-serie…

The ionizing photon budget and effective clumping factor in radiative transfer simulations calibrated to Lyman-alpha forest data
Shikhar Asthana, Girish Kulkarni, Martin G. Haehnelt +3
Recent JWST observations have allowed for the first time to obtain comprehensive measurements of the ionizing photon production efficiency for a wide range of reio…
