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…
Constraints on primordial black holes from interstellar dust temperature in the Galaxy
A. N. Melikhov, E. V. Mikheeva
The photons emitted by primordial black holes (PBHs) can be a heating factor for interstellar dust. Assuming that dust in the Galaxy has a homogeneous distribution and that PBHs ha…
Constraints on the Number of Primordial Black Holes Due to Interaction with Dust
A. N. Melikhov, E. V. Mikheeva
Photons emitted by primordial black holes (PBHs) due to the Hawking effect are among the factors of interstellar dust heating. Based on the data on the temperature of dust, constra…
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…
