Cosmic Reionization on Computers: Statistics, Physical Properties, and Environments of Lyman Limit Systems at z ∼ 6

The Astrophysical Journal
Lyman limit systems (LLSs) are dense hydrogen clouds with high enough H i column densities to absorb Lyman continuum photons emitted from distant quasars.

The JWST/PASSAGE Survey: Testing Reionization Histories with JWST’s First Unbiased Survey for Lyα Emitters at Redshifts 7.5–9.5

The Astrophysical Journal
Ly α emission is one of a few observable features of galaxies that can trace the neutral hydrogen content in the Universe during the Epoch of Reionization (EoR). To accomplish this, we need an efficient way to survey for Ly α emitters (LAEs) at redshifts

Direction-dependent Effects on Global 21 cm Detection

The Astrophysical Journal
Cosmic dawn represents a critical juncture in cosmic history when the first population of stars emerged. The astrophysical processes that govern this transformation need to be better understood.
