FG20 UVB

Paper available on arXiv

Download the FG20 UV/X-ray background model data (updated 10/27/20 to include a version of the TREECOOL file with photo-heating rates rescaled as in Gaikwad et al. 2020 to better match the observed temperature evolution of the IGM).

HI and HeII photoionization rates vs. redshift for the FG20 model, compared to different observational measurements and previous UVB models (see the paper for details).
