The panels shown here are at 20 percent of the current age of the universe and show a wealth of structure on galactic scales. This simulation will be used to examine the final density profiles of the clusters and the dark halos of galaxies. We will examine the dynamics from multiple angles to see how our view of our own cluster might be biased. The mutual interactions of galaxies will be followed to see the effects of merging in low collisions and destruction by high-velocity passages. We will resimulate this region adding gas dynamics to better follow the evolution of galaxies.
Numerous surveys examine much larger slices of the universe.
We would like to expand both resolution and scale to keep pace with observational surveys. Cyclones are areas of minimum sea level pressure, hundreds of kilometers in size, that are the generators of most of the weather. Ultimately not only are accurate datasets produced, but strongly bound error bars are calculated. The latter are important to scientists who use the data, and who need to know how reliable those data are. It was produced using a Kalman filter, which gives an estimate of the error in the analysis, something not done in traditional mapping schemes.
