The First Galaxies and the Likely Discovery of Their Fossils in the Local Group
Figure 2
The two () panels show slices through the most massive object in the simulation 64L05p2 in RGS02b at and . The box size is comoving Mpc. Each one of the panels shows in log-scale the neutral hydrogen fraction (top left), the molecular fraction (top right), the gas overdensity (bottom left), and the gas temperature (bottom right). The sequence illustrates the evolution of a H dissociation sphere around a single source (panel at ) and the dominance of the H dissociating background at .
