Dark energy models with time-dependent gravitational constant
Two phenomenological models of Λ, viz. Λ ∼ (ȧ/a) and Λ ∼ ä/a are studied under the assumption that G is a time-variable parameter. Both models show that G is inversely proportional to time as suggested earlier by others including Dirac. The models considered here can be matched with observational results by properly tuning the parameters of the models. Our analysis shows that Λ ∼ ä/a model corr...
متن کاملCold dark matter models with a cosmological constant
We use linear and quasi-linear perturbation theory to analyse cold dark matter models of structure formation in spatially flat models with a cosmological constant. Both a tilted spectrum of density perturbations and a significant gravitational wave contribution to the microwave anisotropy are allowed as possibilities. We provide normalizations of the models to microwave anisotropies, as given b...
متن کاملDark Energy and Inflation from Gravitational Waves
In this seven-part paper, we show that gravitational waves (classical and quantum) produce the accelerated de Sitter expansion at the start and at the end of the cosmological evolution of the Universe. In these periods, the Universe contains no matter fields but contains classical and quantum metric fluctuations, i.e., it is filled with classical and quantum gravitational waves. In such evoluti...
متن کاملStrong Gravitational Lensing and Dark Energy Complementarity
In the search for the nature of dark energy most cosmological probes measure simple functions of the expansion rate. While powerful, these all involve roughly the same dependence on the dark energy equation of state parameters, with anticorrelation between its present value w0 and time variation wa. Quantities that have instead positive correlation and so a sensitivity direction largely orthogo...
متن کاملCan Strong Gravitational Lensing Constrain Dark Energy?
We discuss the ratio of the angular diameter distances from the source to the lens, Dds, and to the observer at present, Ds, for various dark energy models. It is well known that the difference of Dss between the models is apparent and this quantity is used for the analysis of Type Ia supernovae. However we investigate the difference between the ratio of the angular diameter distances for a cos...
