​B vs. n
The gray scale is for the thermal pressure vs density plots, and the color scale is the magnetic pressure vs. density plots. The line is T=10K, dotted line = ram pressure of the flows, and dashed line = initial magnetic pressure.

​Spectra
Gravitational energy spectra made by taking the Fourier Transform of Sqrt(-gravitational_energy) to avoid nans, since the gravitational energy was everywhere negative.

​E vs. t Plots
These are all plots of bulk energy in the collision region over time.

This plot shows each of the energies (grav., mag., kinetic), divided by the initial kinetic energy in the collision region. It shows that the dominant energy in the collision region is kinetic.

This plot shows each of the energies (grav., mag., kinetic), divided by their own initial values, showing how much each of the energies change over time. It shows that the gravitational energy has the steepest growth rate of these 3 energies. The curve reaches a peak plateau at about 10 Myr, coinciding with the formation of the first sink.

This plot shows each of the energies (grav., mag.), divided by the kinetic energy at each time; it is an instantaneous view of the ratio of these energies to the kinetic energy in the collision region. It shows that after the steep growth in gravitational energy (after 10 Myr), the gravitational energy remains only at about 25% the kinetic. The magnetic energy remains a much smaller fraction throughout the simulation.
