Conversion of protons to positrons by a black hole
A. D. Dolgov, A. S. Rudenko
The conversion of protons to positrons at the horizon of a black hole (BH) is considered. It is shown that the process may efficiently proceed for BHs with masses in the range $\si…
Cosmic rays from heavy particle decays
E. V. Arbuzova, A. D. Dolgov, A. A. Nikitenko
Multidimensional modification of gravity with a smaller mass scale of the gravitational interaction is considered. Stable by assumption dark matter particles could decay via intera…
Antistars as possible sources of antihelium cosmic rays
Andrey Bykov, Konstantin Postnov, Alexander Bondar +2
A minor population of antistars in galaxies has been predicted by some of non-standard models of baryogenesis and nucleosynthesis in the early Universe, and their presence is not y…
James Webb Space Telescope: data, problems, and resolution
A. D. Dolgov
It is argued that the data presented by Hubble Space Telescope and James Webb Space Telescope, that seem to be at odds with the canonical big bang cosmology, find simple explanatio…
Rates of particle production in gravity and supersymmetry-kind dark matter
E. V. Arbuzova, A. D. Dolgov
Universe heating in -modified gravity is considered. The rates of particle production by the scalaron are calculated for different decay channels. Freezing of massive stable r…
Anti-stars in the Milky Way and primordial black holes
A. D. Dolgov
Astronomical data of the several recent years, which present an evidence in favour of abundant antimatter population in our Galaxy, Milky Way, are analysed. The data include: regis…
