چکیده
The Cold Dark Matter (CDM) model has an elegant simplicitly which makes it very predictive, but when its parameters are xed at their`canonical' values its predictions are in connict 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 nd that CDM models with n = 0:8{0.9 and h = 0:45{0.50 can t the available data. Our \best t" CDM model has n = 0:9, h = 0:45 and C T 2 =C S 2 = 0:7. We discuss the current state of observations which could deenitely rule out this model.

The Friedman equation is solved for a universe containing hot-dark matter and cold dark matter. In this scenario, hot-dark matter drives an accelerating universe no cold dark matter.
متن کاملDetectability of a subdominant density component of cold dark matter
Here we examine the detectability of collisionless dark matter candidates that may constitute not all but only a subdominant component of galactic cold dark matter. We show that current axion searches are not suited for a subdominant component, while direct WIMP searches would not be severely affected by the reduced density. In fact, the direct detection rates of neutralinos stay almost constan...

We study universe models which are intrinsically closed and are full of a quintessence scalar field, besides the Cold Dark Matter component. We use these to depict diverse flat Cold Dark Matter models. With the background geometry specified by the Friedman-Robertson-Walker metric, we include among them the standard Cold Dark Matter, the Cosmological Constant Cold Dark Matter and the Dark Energy...
متن کاملDark Matter and Cold Fractal Clouds
There is strong evidence for a large fraction of dark matter in the Universe. Some of the evidence and candidates for dark matter are reviewed. Dark matter in spiral galaxies may be in the form of cold dense clouds of molecular hydrogen. This model is presented in more detail and perspectives for detecting the cold H2 are discussed.
متن کاملScaling relations of the slightly self-interacting cold dark matter in galaxies and clusters
Recent observations in galaxies and clusters indicate that dark matter density profiles exhibit core-like structures which contradict the numerical simulation results of collisionless cold dark matter. The idea of self-interacting cold dark matter (SICDM) has been invoked to solve the discrepancies between the observations and numerical simulations. In this paper, I derive some important scalin...
