Unusually Large Fluctuations in the Statistics of Galaxy Formation at High Redshift

, 2012
We show that various milestones of high-redshift galaxy formation, such as the formation of the first stars or the complete reionization of the intergalactic medium, occurred at different times in different regions of the universe.

The Ancient Star Formation History of the Extremely Low-mass Galaxy Leo P: An Emerging Trend of a Post-reionization Pause in Star Formation

The Astrophysical Journal
Isolated, low-mass galaxies provide the opportunity to assess the impact of reionization on their star formation histories (SFHs) without the ambiguity of environmental processes associated with massive host galaxies.

The Universe Was Reionized Twice [PDF]

The Astrophysical Journal, 2003
We show the universe was reionized twice, first at z~15-16 and second at z~6. Such an outcome appears inevitable, when normalizing to two well determined observational measurements, namely, the epoch of the final cosmological reionization at z~6 and the density fluctuations at z~6, which in turn are tight ly constrained by Lyman alpha forest ...

Magnetizing the Cosmic Web during Reionization

Galaxies, 2018
Increasing evidence suggests that cosmological sheets, filaments, and voids may be substantially magnetized today. The origin of magnetic fields in the intergalactic medium (IGM) is, however, currently uncertain.

Tantalizing Evidence of Reionization Relics in the eBOSS DR16 Ly$\boldsymbolα$ Forest Correlations: a Preference for Early Reionization [PDF]

arXiv
Cosmic reionization of HI leaves enduring relics in the post-reionization intergalactic medium, potentially influencing the Lyman-$\alpha$ (Ly$\alpha$) forest down to redshifts as low as $z \approx 2$, which is the so-called ''memory of reionization'' effect.
