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…
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…
