S2-star dynamics probing the Galaxy core cluster
N. Galikyan, Sh. Khlghatyan, A. A. Kocharyan +1
The star cluster surrounding the supermassive black hole in the center of Milky Way is probed using the data on the S2 star. The value of precession found at the physics-informed n…
Smearing of primordial gravitational waves
M. Samsonyan, A. A. Kocharyan, V. G. Gurzadyan
A mechanism for smearing of the primordial gravitational waves during the radiation-dominated phase of the evolution of the Universe is considered. It is shown that the primordial…
Neural Network Analysis of S2-Star Dynamics: Extended mass
N. Galikyan, Sh. Khlghatyan, A. A. Kocharyan +1
Physics-informed neural network (PINN) analysis of the dynamics of S-stars in the vicinity of the supermassive black hole in the Galactic center is performed within General Relativ…
