Disk-like galaxies at 4 < z < 7.7 : JWST/NIRCam morphologies revealed by denoising VAE-GCNN classification
S. S. Mirzoyan, A. Avagyan, V. G. Gurzadyan
Understanding the prevalence of disk-like galaxies at very high redshifts is crucial for constraining the early formation of angular momentum-supported structures. The advent of JW…
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…
Cosmic voids and the kinetic analysis. V. Hubble tension, the cosmological constant and aperiodic filaments
V. G. Gurzadyan, N. N. Fimin, V. M. Chechetkin
We study the appearance and specific properties of the structures in the local Universe by means of the Vlasov kinetic technique. We consider the role of the cosmological constant…
Focus Point on Tensions in Cosmology from Early to Late Universe: Part II: New Directions in the Light of Observations from the Most Modern Astronomical Facilities
S. Capozziello, E. Di Valentino, V. G. Gurzadyan
The papers included in this Focus Point collection are devoted to the studies on the cosmological tensions and challenges stimulated by the latest observational data. The first res…
On the Earth's tidal perturbations. II. LARES 2 satellite
V. G. Gurzadyan, I. Ciufolini, H. G. Khachatryan +2
Laser-ranging satellites have proved their efficiency in high precision testing of General Relativity and constraining modified gravity theories proposed to explain the dark sector…
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…
