  bibo_abstract:
  - At redshifts beyond z>6, as the mean fraction of neutral hydrogen x_HI in the
    intergalactic medium (IGM) increases, the line flux of Lyman alpha (Lya) emitters
    can be significantly suppressed, which can result in a decrease in the observed
    number of emitters at a given Lya flux. However, cosmological HII regions surrounding
    the Lya emitting galaxies alleviate these effects. We use simple models of the
    Lya line suppression that incorporate the presence of HII regions to predict the
    overall effect of the Lya absorption on the Lya luminosity function. We find,
    in agreement with other recent studies, that unless ionizing sources are unusually
    strongly clustered, a fully neutral IGM may be inconsistent with the large abundance
    of confirmed z=6.5 Lya emitters. However, the presence of local HII regions prohibits
    placing a tight constraint on the mean neutral fraction. We find x_HI < 0.25;
    the presence of strong winds and/or the clustering of ionizing sources would further
    weaken this constraint. We conclude that the evolution of the Lya LF is consistent
    with reionization occurring near this redshift. Finally, we suggest that a measurement
    of observed Lya line width as a function of the Lya luminosity, in a future, larger
    sample of Lya emitters, may serve as a robust diagnostic of the neutral fraction
    in the IGM.@eng
