The projected gas temperature at z = 12.7, just before the stellar cluster turns on. Shown at left is the entire 1.4 Mpc (comoving) simulation box. The region of highest resolution is in the center of our multi-grid simulation box; magnified at right is the central ~ 10 kpc (physical), where the ~ 108 Msun dark matter halo hosting the stellar cluster is located. Note that the gas is heated to ≤ 104 K when passing through the virialization shock.
