Research output: Contribution to journalArticlepeer-review


We investigate the possibility of constraining the ionization state of the Intergalactic Medium (IGM) close to the end of re-ionization (z6) by measuring the size of the H II regions in high-z quasars spectra, via a combination of SPH and 3D radiative transfer (RT) simulations and a statistical analysis of mock quasar spectra through the simulated cosmological volume.
