Ramping Up the Resolution

Digital Cosmology Timeline

Earlier Princeton-NCSA simulations clearly showed what could be achieved with increased computer memory and speed. But the resolution in the first simulation was still far short of that required to compute structures on the scale of individual galaxies or smaller.

In an effort to increase resolution, Frank Summers (now at Princeton University) has since employed different algorithms to run on NCSA's SGI Power Challenge, focusing the calculations in smaller volumes on the scale of galaxy clusters.

Preliminary results are very encouraging. When the data is animated, small, disk-like structures are clearly visible where galaxies would form from cosmic gas that has already cooled somewhat, in contrast to the super-hot gas simulated in the mixed dark matter plus gas models described elsewhere in this exhibit.
