A Census of the LyC Photons that Form the UV Background During Reionization

Abstract:

We present a new, on-the-fly photon flux and absorption tracer algorithm designed to directly measure the contribution of different source populations to the metagalactic ultraviolet (UV) background and to the ionization fraction of gas in the Universe. We use a suite of multifrequency radiation hydrodynamics simulations that are carefully calibrated to reproduce a realistic reionization history and galaxy properties at z ⩾ 6, to disentangle the contribution of photons emitted by different ma...
