Cold Dark Matter and Gas: Gas Temperature Evolution

In these experiments, baryonic gas was modelled on a Convex C3880 and later, a Connection Machine 5 for it fluid behavior under the gravitational influence of dark matter, though no dark matter was "present" in the simulation, thus keeping it as simple as possible. Nevertheless, distinct patterns in the density and temperature of the gas to emerge during the course of the simulation in the slice of the universe depicted. The tests laid the groundwork for further simulations in which mixed dark matter was introduced and its effects on the distribution of baryonic matter modelled in all three spatial dimensions.
