Temperature maps of the post-reionised IGM at z = 3. From top-left to bottom-right the panels correspond to the power-law, mini-quasar, starburst, and hybrid source specta. The source is to the left. Cool (dark) streaks are shadowed regions. Hot streaks are regions recently unshadowed as the ionisation front breaks through a clump.
The volume-weighted temperature distribution at z = 3 for the ionised gas only. From top-left to bottom-right the panels correspond to the power law, mini-quasar, starburst, and hybrid model. The colours/line type distinguish the redshift at which the source turns on, with z_on = 8 (black/dash-dot), zon = 12 (red/dashed), and zon = 20 (blue/solid). The dashed and solid lines nearly coincide. Note the change in the temperature scale for the starburst model.
