(Re)Solving reionization with Lyα: how bright Lyα Emitters account for the z ≍ 2-8 cosmic ionizing background
The cosmic ionizing emissivity from star-forming galaxies has long been anchored to UV luminosity functions. Here, we introduce an emissivity framework based on Lyα emitters (LAEs), which naturally hones in on the subset of galaxies responsible for the ionizing background due to the intimate connection between production and escape of Lyα and LyC
