Gravitational Fields and Dark Matter
when the curvature of space is negative (L is the Lobachevskij constant). For obtaining a potential of Newton (or Coulomb) It is necessary to put c2 = −c1/L, L → ∞ (c2 = −c1/R, R → ∞). Let’s consider hereinafter, that at availability of the space curvature to be obliged non-zero, owing to what the Newton potential should be exchanged by a potential (1), in which c2 = −c1/L And to which one actu...
متن کاملDark Matter and Gravitational Lensing
The last decade has shown a considerable development of gravitational lensing for cosmology because it probes the amount and the nature of dark matter, and provides information on the density parameter Ω, the cosmological constant Λ and the Hubble constant Ho. Therefore, gravitational lensing can constrain the cosmological scenario which gave birth to the Universe as it appears today. The ongoi...
متن کاملGravitational Excitons as Dark Matter ∗
In earlier work it was pointed out that for warped product spacetimes the conformal (geometrical moduli) excitations of the internal compactified factor spaces should be observable as massive scalar fields in the external spacetime. Here we show that these scalar fields (gravitational excitons) describe weakly interacting particles and can be considered as dark matter component. Masses of the g...
متن کاملTesting dark matter with high-redshift supernovae
Dark matter in the Universe consisting of macroscopic objects such as primordial black holes may cause gravitational lensing of distant objects. The magnification associated with lensing will lead to additional scatter in the received flux from standard candles, and too small an observed scatter could rule out compact dark matter entirely. In this letter, we show how the scatter in fluxes of di...
متن کاملTesting Cold Dark Matter Models at Moderate to High Redshift
The COBE microwave background temperature fluctuations and the abundance of local rich clusters of galaxies provide the two most powerful constraints on cosmological models. When all variants of the standard cold dark matter (CDM) model are subject to the combined constraint, the power spectrum of any model is fixed to ∼ 10% accuracy in both the shape and overall amplitude. These constrained mo...
