Revised Active Galactic Nuclei Spectral Model Reveals a More Significant Role in Cosmic Reionization

The Astrophysical Journal Letters
Reionization marks one of the most important phase transitions in the history of the Universe, during which neutral baryonic matter was transformed into ionized plasma.

Efficient modeling of Lyman-α opacity fluctuations during the late reionization epoch

Astronomy & Astrophysics
The Lyman-α forest opacity fluctuations observed from high-redshift quasar spectra have been proven to be extremely successful in probing the late phase of the reionization epoch.

A dense web of neutral gas in a galaxy proto-cluster post-reionization

Galaxy clusters are the most massive, gravitationally bound structures in the Universe. They emerged through hierarchical structure formation of large-scale dark matter and baryon overdensities.

Behavior of the Lyα Damping Wings as a Function of Reionization Topology

The Astrophysical Journal
The damping wing signatures in high-redshift quasars have proven instrumental in studying the epoch of reionization. With the upcoming Euclid mission set to discover many more quasars, it is crucial to explore what this new set of quasars might reveal ...

Prospects for kSZ2–21 cm2 Cross Correlations during Reionization

The Astrophysical Journal
The 21 cm line and the patchy kinetic Sunyaev–Zel’dovich (kSZ) effect are promising and complementary probes of the Epoch of Reionization. A challenge for cross correlating these two signals is that foreground avoidance or removal algorithms applied to ...
