Spatial distribution of escaping photons (top) and absorbed photons (bottom) for the snapshot at 1/1.5/2 Gyr (left/center/right). For the transmitted photons, the distribution is given by the points in the simulation box where photons scattered just before it left the box. For the destroyed Lyα photons, we binned the positions at which photons were absorbed. Each plot shows the central 40 kpc of the disk.
