Time-dependent fluctuations in the metagalactic photoionization background
Avery Meiksin, Matthew McQuinn
We present a formalism for computing time-dependent fluctuations in the cosmological photoionizing radiation background, extending background fluctuations models beyond the steady-…
Estimates for the impact of Ultraviolet Background fluctuations on galaxy clustering measurements
Phoebe Upton Sanderbeck, Vid Irsic, Matthew McQuinn +1
Spatial fluctuations in ultraviolet backgrounds can subtly modulate the distribution of extragalactic sources, a potential signal and systematic for large-scale structure surveys.…
The Impact of Neutral Intergalactic Gas on Lyman- Intensity Mapping During Reionization
Eli Visbal, Matthew McQuinn
We present the first simulations of the high-redshift Ly intensity field that account for scattering in the intergalactic medium (IGM). Using a 3D Monte Carlo radiative transfer…
Heating of the Intergalactic Medium by Hydrogen Reionization
Anson D'Aloisio, Matthew McQuinn, Oliver Maupin +4
During reionization, the intergalactic medium is heated impulsively by supersonic ionization fronts (I-fronts). The peak gas temperatures behind the I-fronts, , a…
The observable 21cm signal from reionization may be perturbative
Matthew McQuinn, Anson D'Aloisio
We develop an effective perturbation theory (and, equivalently, a bias expansion) for the inhomogeneous 21cm radiation field from reionization. Using large-scale simulations of cos…
Absorber Model: the Halo-like model for the Lyman-alpha forest
Vid Iršič, Matthew McQuinn
We present a semi-analytic model for the Lyman- forest that is inspired by the Halo Model. This model is built on the absorption line decomposition of the forest. Flux correlati…
