Box 64 – 186592 – Warm Dark Matter

Since there still remain problems with the small scale structure in simulations with cold dark matter, we also made a corresponding simulation of our Local Universe using warm dark matter. The outcome can be compared directly to simulations of Box 64 - 186592.

The table below provides the general cosmological parameters:
