Figure 1a Dark matter plus gas run. Dark matter particles within a cube of 300 physical kpc on a side shown at redshift z=0 and projected according to the angular momentum of the dark matter only run (fig2b, right). Each particle is colored according to its potential energy. Figure 2a Dark matter only run. Dark matter particles within a cube of 300 physical kpc on a side shown at redshift z=0 and projected according to the angular momentum of the dark matter halo. Each particle is colored according to its potential energy. Figure 3a Dark matter plus gas super high res run. Dark matter particles within a cube of 150 physical kpc on a side shown at redshift z=0 and projected according to the angular momentum of the dark matter only run (fig2b, right). Each particle is colored according to its potential energy. Figure 4a Dark matter only super high res run. Dark matter particles within a cube of 150 physical kpc on a side shown at redshift z=0 and projected according to the angular momentum of the dark matter halo. Each particle is colored according to its potential energy. Figure 5a Dark matter plus gas super high res run. Dark matter particles within a cube of 50 physical kpc on a side shown at redshift z=0 and projected according to the angular momentum of the dark matter only run (fig2b, right). Each particle is colored according to its potential energy. Figure 6a Dark matter only super high res run. Dark matter particles within a cube of 50 physical kpc on a side shown at redshift z=0 and projected according to the angular momentum of the dark matter halo. Each particle is colored according to its potential energy.
