Ricci Focusing Degeneracy between Dynamical Dark Energy and Matter Inhomogeneity
I. A. Moiseev, O. S. Sazhina
The influence of dynamical (phantom) dark energy on light propagation within the framework of the Zeldovich-Kantowsky-Dyer-Roeder (ZKDR) approximation is discussed. This effect is…
Estimates of the Dynamic Characteristics of Binary Systems for Traversable Wormholes Search
I. A. Moiseev, O. S. Sazhina
The paper presents simulated detectability of traversable wormholes (WHs) in wide binary astrophysical systems without accretion (dormant binary systems) and in the Galactic center…
Deep Photometry of Suspected Gravitational Lensing Events: Potential Detection of a Cosmic String
Margarita Safonova, Igor I. Bulygin, Olga S. Sazhina +3
Cosmic strings (CS) are one-dimensional cosmological-size objects predicted in realistic models of the early Universe. Analysis of the cosmic microwave background (CMB) anisotropy…
Theory of gravitational lensing on a curved cosmic string
Igor I. Bulygin, Mikhail V. Sazhin, Olga S. Sazhina
It is discussed in detail the complete mathematical model of gravitational lensing on a single cosmic string (CS) of general shape and position with respect to the line of sight. C…
On mass distribution of coalescing black holes
A. D. Dolgov, A. G. Kuranov, N. A. Mitichkin +4
Available data on the chirp mass distribution of the coalescing black hole binaries in O1-O3 LIGO/Virgo runs are analyzed and compared statistically with the distribution calculate…
Optical analysis of a CMB cosmic string candidate
O. S. Sazhina, D. Scognamiglio, M. V. Sazhin +1
The complexity of the cosmological scenario regarding cosmic strings (CSs) stands still in the way of a complete understanding. We describe here a promising strategy for the possib…
