Dwarf Galaxies in Voids: Dark Matter Halos and Gas Cooling

Figure 8

Left panels: The density-temperature 𝑇(Δ,𝑡) for several redshifts and three different UV-background models. The next three columns show the redshift evolution of the parameters of 𝑇(Δ,𝑡): The normalisation and the effective e.o.s., 𝑇₀, the position of the maximum, Δ_max, and the slope of the e.o.s., 𝛼. Finally, for each UV-background model the resulting characteristic circular velocity is shown, see (22). The upper right panel shows also the characteristic velocity obtained from the numerical simulations.
