Kolmogorov analysis of pulsar TOA
N. Galikyan, A. A. Kocharyan, V. G. Gurzadyan
The Kolmogorov stochasticity parameter (KSP) as a sensitive descriptor of the degree of randomness of signals was used to analyze the properties of the NANOGrav pulsar timing data…
Kolmogorov analysis of JWST deep survey galaxies
N. Galikyan, A. A. Kocharyan, V. G. Gurzadyan
JWST galaxy deep spectral surveys provide a unique opportunity to trace a broad range of evolutionary features of galaxies and the intergalactic medium given the huge distance the…
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…
