The projection of the density of matter (in colors) in a cosmological simulation is over-plotted with the locations of dark matter particles (black dots) that are halo members. The numbers of particles in each halo, along with circles with radius equal to the maximum for each halo, is over-plotted. Volume rendering of density with an isometric view of a (32 Mpc/h)3 volume and a red light source. Vorticity, plotted using a user-defined field via a finite stencil requiring an extra ghost zone in every direction Density Isocontours in a Cosmology simulation 2D Sedov Blast Wave A cutting plane image, aligned with the spherically-averaged angular momentum vector, through the disk of a primordial star forming region A shell-based, software-rendered volume rendering of a Population III star-forming halo. The two fragmenting clumps are separated by approximately 800AU, and semi-analytic calculations suggest they will form a binary star system. Velocity vectors overlaid on top of a slice showing the mach number of a collapsing and rotating star forming region. A phase diagram showing the distribution of mass in the Density-Temperature plane in a collapsing pre-stellar cloud. 10,000AU wide slice through a metal-enriched star forming region, with temperature contours overlaid.
