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. WebOct 20, 1998 · Abstract. The next generation of cosmic microwave background (CMB) experiments, galaxy surveys, and high-redshift observations can potentially determine the nature of the dark matter observationally. With this in mind, we introduce a phenomenological model for a generalized dark matter (GDM) component and discuss …
