Lense-Thirring precession and gravito-gyromagnetic ratio
A. Stepanian, Sh. Khlghatyan, V. G. Gurzadyan
The geodesics of bound spherical orbits i.e. of orbits performing Lense-Thirring precession, are obtained in the case of the -term within gravito-electromagnetic formalism. It i…
The Djorgovski-Gurzadyan dark energy integral equation and the Hubble diagram
H. G. Khachatryan, A. Stepanian
We consider the observational aspects of the value of dark energy density from quantum vacuum fluctuations based initially on the Gurzadyan-Xue model. We reduce the Djorgovski-Gurz…
Lense-Thirring precession and modified gravity constraints
A. Stepanian, Sh. Khlghatyan
The orbital Lense-Thirring precession is considered in the context of constraints for weak-field General Relativity involving the cosmological constant . It is shown that accord…
Galactic sparsity and -gravity
A. Amekhyan, S. Sargsyan, A. Stepanian
The sparsity parameter for clusters of galaxies is obtained in the context of -gravity. It is shown that, the theoretical estimated values are within the reported error limits o…
On the Lambda-evolution of galaxy clusters
V. G. Gurzadyan, A. A. Kocharyan, A. Stepanian
The evolution of galaxy clusters can be affected by the repulsion described by the cosmological constant. This conclusion is reached within the modified weak-field General Relativi…
