Dark matter structure formation
WebFinally, we present analysis of structure formation in the latest in a series of state-of-the-art fully-coupled radiation-hydrodynamics simulations of reionisation, containing 81923 dark matter particles and cells. We present a comparison to a companion dark matter-only simulation, finding good agreement at low redshifts and high masses.
