Origin of monolithic high-z galaxies and UV luminosity of mergering high-z galaxies in the cosmological model with non-standard spectrum of density perturbations
Yu. N. Eroshenko, V. N. Lukash, E. V. Mikheeva +2
The James Webb Space Telescope (JWST) has detected an unexpectedly large number of galaxies at redshifts compared to the predictions of the standard CDM model. One o…
Absorption in the 21 cm Hydrogen Line at as a Sensitive Tool for the Construction of a Cosmological Model on Small Scales
Yu. N. Eroshenko, V. N. Lukash, E. V. Mikheeva +2
The cosmic microwave background absorption intensity in the 21 cm line of neutral hydrogen in the presence of additional power in the form of a "bump" in the spectrum of cosmologic…
High- SMBHs in Cosmological Models with Enhanced Power Spectra
M. V. Tkachev, S. V. Pilipenko, E. V. Mikheeva +1
We consider the impact of non-power-law spectra of matter perturbations with a bump or with a blue tilt at small scales on the evolution of supermassive black holes (SMBHs) located…
Cascade Relaxation of the Gravitating Vacuum as a Generator of the Evolving Universe
V. N. Lukash, E. V. Mikheeva
The cascade relaxation of a polarized vacuum in the expanding Universe is a chain of evolutionary epochs of decreasing its density with the exit of dominant fields (each in its own…
Origin of cosmological density perturbations from quantum fluctuations of vacuum in General Relativity
Vladimir N. Lukash, Elena V. Mikheeva
After 45 years since the discovery of quantum-gravitational birth of the cosmological density perturbations we can try to answer the main question of cosmology what is the origin o…
Inner structure of dark matter halos at high in cosmological models with non-power-law primordial spectra
M. V. Tkachev, S. V. Pilipenko, E. V. Mikheeva +1
We consider three cosmological models with non-power-law spectra of primordial density perturbations and test them against CDM in density profiles of dark matter halos. We foun…
