Cosmic voids and induced hyperbolicity. III. tracing redshift dependence
M. Samsonyan, A. A. Kocharyan, A. Stepanian +1
The currently released datasets of the observational surveys reveal the redshift dependence of the physical features of cosmic voids. We study the void induced hyperbolicity, that…
Cosmological constant, information and gedanken experiments with black hole horizons
V. G. Gurzadyan, A. Stepanian
The cosmological constant if considered as a fundamental constant, provides an information treatment for gravitation problems, both cosmological and of black holes. The efficiency…
Cosmic voids and induced hyperbolicity. II. Sensitivity to void/wall scales
M. Samsonyan, A. A. Kocharyan, A. Stepanian +1
Cosmic voids as typical under-density regions in the large scale Universe are known for their hyperbolic properties as an ability to deviate the photon beams. The under-density the…
Hubble tension vs two flows
V. G. Gurzadyan, A. Stepanian
The Hubble tension is shown to be solvable, without any free parameter, conceptually and quantitatively, within the approach of modified weak-field General Relativity involving the…
Black hole shadow to probe modified gravity
A. Stepanian, Sh. Khlghatyan, V. G. Gurzadyan
We study the black hole's shadow for Schwarzschild - de Sitter and Kerr - de Sitter metrics with the contribution of the cosmological constant Λ. Based on the reported parameters o…
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…
