Abstract
Conclusions. These results support a scenario where high redshift, relatively bright (L >= 0.5L*) star-forming galaxies alone are unable to sustain the level of ionization observed in the cosmic intergalactic medium at z 3. Star-forming galaxies at higher redshift and at fainter luminosities (L << L*) can only be major contributors to the reionization of the Universe if their physical properties are subject to rapid changes from z 3 to z similar to 6-10. Alternatively, ionizing sources could he discovered looking for fainter sources among the active galactic nuclei population at high redshift.
