Messier 90 galactic halo rotation in the microwaves
F. De Paolis, V. G. Gurzadyan, A. L. Kashin +4
We used Planck data to study the Virgo Cluster's galaxy M 90 and its surroundings. We find, as in the case of certain galaxies of the Local Group and its vicinity, a substantial te…
Cosmic voids and the kinetic analysis. II. Link to Hubble tension
V. G. Gurzadyan, N. N. Fimin, V. M. Chechetkin
We consider a principal problem, that of the possible dominating role of self-consistent gravitational interaction in the formation of cosmic structures: voids and their walls in t…
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…
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…
