Method for Determining the Parameters of a Ring-like Structure from the Visibility Function Shape
S. V. Chernov, M. A. Shchurov, I. I. Bulygin +1
Black hole images obtained by very long baseline interferometry (VLBI) by the Event Horizon Telescope are a new tool for testing general relativity in super-strong gravitational fi…
Estimation of Orbital Parameters from (u,v)-coverage for a Space Radio Interferometer
I. I. Bulygin, M. A. Shchurov, A. G. Rudnitskiy
Finding a suitable very long baseline (VLBI) interferometer geometry is a key task in planning observations, especially imaging sessions. The main characteristic of the quality of…
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…
