Damping Wing-Like Features in the Stacked Ly𝛼 Forest: Potential Neutral Hydrogen Islands at 𝑧 < 6 (2024)
Journal Article

Recent quasar absorption line observations suggest that reionization may end as late as z ≈ 5.3. As a means to search for large neutral hydrogen islands at z &amp;lt; 6, we revisit long dark gaps in the Lyβ forest in VLT/X-Shooter and Keck/ESI quasar...

JWST observations of galaxy damping wings during reionization interpreted with cosmological simulations (2024)
Journal Article

Spectra of the highest redshift galaxies taken with JWST are now allowing us to see into the heart of the reionization epoch. Many of these observed galaxies exhibit strong damping wing absorption redward of their Lyman-α emission. These observations...

The origin of the characteristic shape and scatter of intergalactic damping wings during reionization (2024)
Journal Article

Ly α damping wings in the spectra of bright objects at high redshift are a useful probe of the ionization state of the intergalactic medium during the reionization epoch. It has recently been noted that, despite the inhomogeneous nature of reionizati...

Particle initialization effects on Lyman- αforest statistics in cosmological SPH simulations (2024)
Journal Article

Confronting measurements of the Lyman- αforest with cosmological hydrodynamical simulations has produced stringent constraints on models of particle dark matter and the thermal and ionization state of the intergalactic medium. We investigate the robu... Read More about Particle initialization effects on Lyman- αforest statistics in cosmological SPH simulations.

Unveiling dark matter free streaming at the smallest scales with the high redshift Lyman-alpha forest (2024)
Journal Article

This study introduces novel constraints on the free streaming of thermal relic warm dark matter (WDM) from Lyman-α forest flux power spectra. Our analysis utilizes a high resolution, high redshift sample of quasar spectra observed using the HIRES and...
