Cold Dark Matter Resuscitated?
Abstract
The Cold Dark Matter (CDM) model has an elegant simplicitly which makes it very predictive, but when its parameters are fixed at their `canonical' values its predictions are in conflict with observational data. There is, however, much leeway in the initial conditions within the CDM framework. We advocate a re-examination of the CDM model, taking into account modest variation of parameters from their canonical values. We find that CDM models with --0.9 and --0.50 can fit the available data. Our ``best fit'' CDM model has , and . We discuss the current state of observations which could definitely rule out this model.
