Gravitational waves with dark energy

چکیده
In this article, we study the tensor mode equation of perturbation in presence nonzero-Lambda as dark energy, dynamic nature which depends on Hubble parameter H and/or its time derivative. Dark according to total vacuum contribution, has a slight effect during radiation-dominated era, but it reduces squared amplitude gravitational waves (GWs) up 60% for wavelengths that enter horizon matter-dominated era.

Dark 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...
متن کاملAnalytic spectrum of relic gravitational waves modified by neutrino free streaming and dark energy
We include the effect of neutrino free streaming into the spectrum of relic gravitational waves (RGWs) in the currently accelerating universe. For the realistic case of a varying fractional neutrino energy density and a non-vanishing derivative of mode function at the neutrino decoupling, the integrodifferential equation of RGWs is solved by a perturbation method for the period from the neutrin...
متن کاملDark 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...
