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:

L_box		64 Mpc/h
Ω_Λ		0.76
Ω_m		0.24
Ω_bar		0.0418
h		0.73
σ₈		0.75
n		0.95
iseed		186592
spectrum		EisHu approximation with an exponential cut-off according to a 1keV WDM particle (jpg [130 KB])
