Radial profiles for column density, emissivity, luminosity and flux for various background UV fields. The upper left panel shows the column density radial profile of the halo. The emissivity radial profile for the halo is depicted in the upper right panel, where the dot-dashed line shows the Lyman alpha emissivity and the triple dot-dashed line shows the total emissivity of all the coolants. The lower left panel shows the luminosity radial profile. The flux radial profile of the halo is depicted in the lower right panel. All panels in this figure have an escape fraction of 1% for ionizing photons.
