Luminosity Functions of Lyα Emitters at Redshifts z = 6.5 and z = 5.7: Evidence against Reionization at z ≤ 6.5
Open accessAbstract
The visibility of Lyα emission from galaxies should be suppressed substantially by a neutral intergalactic medium before reionization. Even after taking into account a local H II region produced by the galaxy and a velocity offset of Lyα, a factor of 3 attenuation in the line is unavoidable. We rule out such a suppression by comparing line luminosity functions of Lyα emitters at z = 6.5 and 5.7. The luminosity functions at z = 5.7 and z = 6.5 were constructed using published surveys over a range of depths and volumes. They constrain both characteristic luminosity L * and density ϕ * . The luminosity functions at the two redshifts are statistically consistent with one another, and only one survey lies substantially off the luminosity function. We conclude that reionization was largely complete at z ≈ 6.5.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
