Density weighted projection of gas density for different background UV fields and dust-to-gas ratios at redshift 5.4. The top left panel shows the density for model A. The density structure for model B is shown in the upper right panel. The bottom left panel shows the density structure for model C while the bottom right panel shows the density structure for model D. The escape fraction of ionizing radiation is 10% for all the panels. The values of density shown in the colorbar are in comoving units [g/cm³].
