Unveiling Dark Matter free-streaming at the smallest scales with high redshift Lyman-alpha forest
Vid Iršič, Matteo Viel, Martin G. Haehnelt +8
This study introduces novel constraints on the free-streaming of thermal relic warm dark matter (WDM) from Lyman- forest flux power spectra. Our analysis utilises a high-resolut…

Measuring the photo-ionization rate, neutral fraction and mean free path of HI ionizing photons at from a large sample of XShooter and ESI spectra
Prakash Gaikwad, Martin G. Haehnelt, Frederick B. Davies +16
We measure the mean free path (), photo-ionization rate () and neutral fraction () of hydrogen in 12 redshif…

ARTIST: Fast radiative transfer for large-scale simulations of the epoch of reionisation
Margherita Molaro, Romeel Davé, Sultan Hassan +2
We introduce the "Asymmetric Radiative Transfer In Shells Technique" (ARTIST), a new method for photon propagation on large scales that explicitly conserves photons, propagates pho…
