Evolution of the Observed Ly-alpha Luminosity Function from z = 6.5 to z = 7.7: Evidence for the Epoch of Re-ionisation?
Probing the first billion years of the Universe is one of the last frontiers in cosmology. Ly-alpha emitters (LAEs) are galaxies that can be detected out to very high redshifts during the epoch of re-ionisation. The evolution of their luminosity function with redshift is a direct probe of the Ly-alpha transmission of the intergalactic medium (IGM)
