  - For a source of Lyα radiation embedded in a neutral intergalactic medium (IGM)
    prior to the reionization epoch, the Lyα emission line is strongly suppressed
    by the intervening IGM. The damping wing of the so-called Gunn-Peterson trough
    can extend to the red side of the emission line and erase a significant fraction
    of the total line flux. However, the transmitted fraction increases with the size
    of the local cosmological H II region surrounding the source, and therefore with
    the ionizing luminosity and age of the source. Motivated by the recent discovery
    of a Lyα-emitting galaxy at a redshift z = 6.56 (Hu et al.), possibly prior to
    the reionization of the IGM, we revisit the effects of a neutral IGM on the Lyα
    emission line. We show that for faint sources with little or even no ionizing
    continuum, a sufficiently broad (Δv ≳ 300 km s^-1) emission line can still remain
    observable. In particular, the line detected by Hu et al. is consistent with a
    source embedded in a neutral IGM. We provide characterizations of the asymmetry
    and total transmitted flux of the Lyα line as functions of the ionizing emissivity
    of its source. We argue that a statistical sample of Lyα emitters extending beyond
    the reionization redshift can be a useful probe of reionization.@eng
