Collision Movies

A subcluster of mass 4.7×10¹³ M₀ was collided with a cluster of mass 1.4×10¹⁵ M₀ using the hydro/N-body code, Hydra (Couchman et al, 1995), which models the hydrodynamics using smoothed particle hydrodynamics (SPH).

The simulations involved 200,000 particles split almost 50/50 into dark matter and gas.
