Dwarf Galaxies in Voids: Dark Matter Halos and Gas Cooling
Figure 9
Theoretical results for temperature distribution in the IGM as a result of different UVB heating models. (a) The thick solid line indicate the result for our standard model according to [73]. Color coded is the cooling time. The blank area indicates the region where the gas is heated. Three contour lines are shown, they indicate from the left to right a cooling time 10x, 1x, and 0.1x the Hubble time. The dashed blue line indicates a four times increased energy per ionising photon only for . (b) Results for four times increased energy per ionising photon for all redshifts. For comparison the dashed blue line indicates temperature distribution resulting from the standard model as shown in (a). (c) Results for ten times increased energy per ionising photon for all redshifts. For comparison also the eight times increased energy and the standard heating as shown in (a) are indicated.
