Title of your presentation : Reionization effects on Ly_alpha spectra

In the last few years an increasing interest has been devoted to the search of Ly_alpha emitters at high redshift.
In order to investigate this issue we developed a code where Ly_alpha photons are propagated together with the ionizing continuum, since the visibility of Ly_alpha emission from galaxy depends on local HII regions produced by the ionizing radiation.
This approach allows to investigate the effects of evolving ionization configurations on the propagation of Ly_alpha radiation and on the shaping of the line emerging from single objects.
