چکیده
I review axions, neutralinos, axinos, gravitinos and super-massive Wimpzillas as dark matter candidates.

Formation of Large Structures in the Acceleration Universe with a Hybrid Expansion Law
In the current paper, we have studied the effect of dark energy on for-mation where dark energy exists in the background. For this purpose, we used both WMAP9 and Planck data to study how the radius changes with redshift in these mod-els. We used different data sets to fix the cosmological parameters to obtain a solution for a spherical region under collapse. The mechanism of structure formation f...
متن کاملExperimental Searches for Non - Baryonic Dark Matter : WIMP Direct Detection
Experimental observations and robust theoretical arguments have established that our universe is essentially non-visible, the luminous matter scarcely accounting for one per cent of the energy density of a flat universe. The distribution of a flat universe (Ω = ΩM + ΩΛ = 1) attributes to the dark energy about ΩΛ ∼ 70%, whereas the matter density takes the remaining ΩM ∼ 30%, consisting of, both...

Several lines of evidence suggest that some of the dark matter may be nonbaryonic: the non-detection of various plausible baryonic candidates for dark matter inferred, e.g., from galaxy rotation curves and from cluster of galaxy velocity dispersions, the need for non-baryonic dark matter for theoretical models of galaxy formation, and the large discrepancy between dynamical measurements implyin...
متن کاملNon-Baryonic Dark Matter
These lectures on non-baryonic dark matter matter are divided into two parts. In the first part, I discuss the need for non-baryonic dark matter in light of recent results in cosmology, and I present some of the most popular candidates for non-baryonic dark matter. These include neutrinos, axions, neutralinos, WIMPZILLAs, etc. In the second part, I overview several observational techniques that...
متن کاملWhy Do We Need Non - Baryonic Dark Matter ?
Observational evidence along with theoretical arguments which call for non-baryonic dark matter are reviewed. A brief summary of the dark matter session is included. There is increasing evidence that relative to the visible matter in the Universe, which is in the form of baryons, there is considerably more matter in the Universe that we don’t see [1]. Here, I will review some of the motivations...
