Schematic illustration of our two-zone photoionization models for LyC emitters, combining an ionization region with density-bounded regions chosen to have different ionization parameters (“high” and “low” U). In the “density-bounded channels” scenario, ionizing photons escape from the low-U region, while in the “density-bounded galaxy” scenario, they escape from the high-U region with f_esc = 0 for the nonleaking region and f_esc between 0% and 80% for the leaking region.
