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…
An adaptive algorithm for detecting double stars in astrometric surveys
Mikhail V. Sazhin, Valerian Sementsov, Sergey Sorokin +2
The paper develops a method for detecting optical binary stars based on the use of astrometric catalogs in combination with machine learning (ML) methods. A computational experimen…
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…
TianQin: a space-borne gravitational wave detector
Jun Luo, Li-Sheng Chen, Hui-Zong Duan +17
TianQin is a proposal for a space-borne detector of gravitational waves in the millihertz frequencies. The experiment relies on a constellation of three drag-free spacecraft orbiti…
General relativistic laser interferometric observables of the GRACE-Follow-On mission
Slava G. Turyshev, Mikhail V. Sazhin, Viktor T. Toth
We develop a high-precision model for laser ranging interferometric (LRI) observables of the GRACE Follow-On (GRACE-FO) mission. For this, we study the propagation of an electromag…
