Radial profiles for temperature and species fractions for various background UV fields with higher escape fractions of ionizing radiation. The upper left panel of this figure shows the temperature radial profile of the halo. The HII abundance radial profile for the halo is depicted in the upper right panel. H₂ abundance is shown in the lower left panel. The HeII radial profile of the halo is depicted in the lower right panel. The legend in each panel shows the values of the escape fraction of ionizing photons and the strength of the background radiation field.
