On intrinsic symmetry in Gurzadyan-Xue cosmological models
H. Khachatryan, G. V. Vereshchagin, G. Yegorian
Analysis of cosmological solutions of GX dark energy models shows the presence of a separatrix in the phase space of solutions which divides them into two classes: Friedmannian-lik…
Dynamics of perturbations in Gurzadyan-Xue cosmological models
G. V. Vereshchagin, G. Yegorian
Perturbation theory within Newtonian approximation is presented for cosmological models with varying physical constants. Analytical solutions for perturbations dynamics are obtaine…
Supernovae and Radio Galaxies Probing Gurzadyan-Xue Cosmological Models with Dark Energy
G. V. Vereshchagin, G. Yegorian
In the previous papers we derived cosmological equations for models with Gurzadyan-Xue dark energy, have performed their qualitative analysis and, particularly, have revealed a rem…
Hidden invariance in Gurzadyan-Xue cosmological models
G. V. Vereshchagin, G. Yegorian
The dark energy formula derived by Gurzadyan and Xue which leads to a value fitting the SN data, provides a scaling relation between the physical constants and cosmological paramet…
Cosmological models with Gurzadyan-Xue dark energy
G. V. Vereshchagin, G. Yegorian
The formula for dark energy density derived by Gurzadyan and Xue provides a value of density parameter of dark energy in remarkable agreement with current cosmological datasets, un…
