Artist: Fast radiative transfer for large-scale simulations of the epoch of reionization
(Oxford University Press, 2019)We introduce the ‘Asymmetric Radiative Transfer In Shells Technique’ (ARTIST), a new method for photon propagation on large scales that explicitly conserves photons, propagates photons at the speed of light, approximately ... -
A full treatment of peculiar velocities on the reionization light cone
(Oxford Academic, 2019)Accurate simulations of the 21-cm signal from the Epoch of Reionization require the generation of maps at specific frequencies given the values of astrophysical and cosmological parameters. The peculiar velocities of the ... -
Semi-analytic forecasts for JWST – IV. Implications for cosmic reionization and LyC escape fraction
(Oxford University Press, 2020-06-20)Galaxies forming in low-mass haloes are thought to be primarily responsible for reionizing the Universe during the first billion years after the big bang. Yet, these haloes are extremely inefficient at forming stars in ... -
Simulations of primary beam effects on the cosmic bispectrum phase observed with the Hydrogen Epoch of Reionization Array
(Royal Astronomical Society, 2022)The 21 cm transition from neutral hydrogen promises to be the best observational probe of the epoch of reionization (EoR). The main difficulty in measuring the 21 cm signal is the presence of bright foregrounds that require ...
