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-α forest statistics in cosmological SPH simulations (2024)
Journal Article
Khan, N. K., Kulkarni, G., Bolton, J. S., Haehnelt, M. G., Iršič, V., Puchwein, E., & Asthana, S. (2024). Particle initialization effects on Lyman-α forest statistics in cosmological SPH simulations. Monthly Notices of the Royal Astronomical Society, https://doi.org/10.1093/mnras/stae662

Confronting measurements of the Lyman-α forest 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-α forest statistics in cosmological SPH simulations.

Unveiling dark matter free streaming at the smallest scales with the high redshift Lyman-alpha forest (2024)
Journal Article
Iršič, V., Viel, M., Haehnelt, M. G., Bolton, J. S., Molaro, M., Puchwein, E., …Kulkarni, G. (2024). Unveiling dark matter free streaming at the smallest scales with the high redshift Lyman-alpha forest. Physical Review D, 109(4), Article 043511. https://doi.org/10.1103/physrevd.109.043511

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...
