论文摘要
检测Lyman-$α$发射星系（LAES）对电离历史施加了严重的限制。在本文中，我们得出了在上一篇文章中仅显示的仅有的两个重离场景中非常高$ z $ laes的特性，与15个独立发展的全球（或平均）宇宙对象的最新数据一致，涉及可变物体的全球（平均宇宙对象），涉及胶质介质以及$ Z = $ z = $ z的电子散射的光学介质，以及一项$ z = $ z = $ z = $ z = $ z = $ z = $ z = $ z n of z $ z的行为，它是$ z的$ z nototic $ z n o s n of z $ z的行为，该介于$ 6通常考虑，另一个具有非单调行为，其中两个完整的电离事件为$ z = 6 $，$ z = 10 $。我们发现，在这两种情况下，非常高的$ z $ laes的Ly $α$光度函数非常不同。因此，将这些预测与诸如James Webb太空望远镜等新工具的观察结果进行比较，应该可以揭示正确的电源场景。同时，我们可以将非常高的$ z $ laes的预测红移分布和紫外线（或Lyman-$α$）的发光度与已经观察到的$ z> 7.5 $的少数物体的液体。通过这样做，我们发现此类数据与单个电源场景有张力，而它们与双重离子场景完全兼容。
The detection of Lyman-$α$ emitting galaxies (LAEs) puts severe constraints on the reionization history. In this Paper we derive the properties of very high-$z$ LAEs predicted in the only two reionization scenarios shown in a previous Paper to be consistent with current data on 15 independent evolving global (or averaged) cosmic properties regarding luminous objects and the intergalactic medium and the optical depth to electron scattering of ionized hydrogen to CMB photons: one with a monotonic behavior, which is completed by $z=6$, as commonly considered, and another one with a non-monotonic behavior with two full ionization events at $z=6$ and $z=10$. We find that the Ly$α$ luminosity functions of very high-$z$ LAEs are very distinct in those two scenarios. Thus, comparing these predictions to the observations that will soon be available thanks to new instruments such as the James Webb Space Telescope, it should be possible to unveil the right reionization scenario. In the meantime, we can compare the predicted redshift distribution and UV (or Lyman-$α$) luminosities of very high-$z$ LAEs to those of the few objects already observed at $z>7.5$. By doing that we find that such data are in tension with the single reionization scenario, while they are fully compatible with the double reionization scenario.
