Red Dwarfs as Sources of Cosmic Rays [PDF]

open access: yesEPJ Web of Conferences, 2022
The Pamela, Fermi, AMS-02 spectrometer experimental data cannot be explained using the diffusive models of propagation of cosmic-rays accelerated at the supernova shocks and require the existence of nearby sources of cosmic rays at the distances less ...

On the Search for the Galactic PeVatrons by Means of Gamma-Ray Astronomy

open access: yesUniverse, 2022
Cosmic rays are ultra-relativistic particles that slam into the atmosphere from all directions in the sky. Gamma rays emitted when cosmic rays interact with Galactic gas and radiation fields are a powerful tool to investigate their origin. Many candidate

Diffuse Emission of Galactic High-energy Neutrinos from a Global Fit of Cosmic Rays

open access: yesThe Astrophysical Journal, 2023
In the standard picture of Galactic cosmic rays, a diffuse flux of high-energy gamma rays and neutrinos is produced from inelastic collisions of cosmic-ray nuclei with the interstellar gas.

SOLAR ACTIVITY AND EARTH SEISMICITY

open access: yesSolar-Terrestrial Physics, 2021
Using the results of continuous long-term observations over 50 years (including solar cycles 20–24), we study the relationship between Earth’s seismicity and solar activity.

Galactic Cosmic Rays: The first detection of TeV gamma-rays from Red Dwarfs [PDF]

open access: yesEPJ Web of Conferences, 2019
The present point of view on the sources of cosmic rays in Galaxy considers explosions of supernovae as sources of these particles up to energies of 1017 eV.

New look on the origin of cosmic rays

open access: yesEPJ Web of Conferences, 2017
From the analysis of the flux of high energy particles, E > 3 · 1018 eV, it is shown that the distribution of the power density of extragalactic rays over energy is of the power law, q̅(E) ∝ E−2.7, with the same index of 2.7 that has the distribution of ...

The GRAND project and GRANDProto300 experiment [PDF]

open access: yesEPJ Web of Conferences, 2019
The Giant Array for Neutrino Detection (GRAND) is a proposal for a giant observatory of ultra-high energy cosmic particles (neutrinos, cosmic rays and gamma rays). It will be composed of twenty subarrays of 10 000 antennas each, totaling a detection area

On irregularities in the cosmic ray spectrum of \(10^{16}-10^{18}\) eV range

open access: yesSciPost Physics Proceedings, 2023
Existing small, medium and large arrays for the study of cosmic rays of ultra-high energies are aimed for obtaining information about our galaxy and extragalactic space, namely to search and study astronomical objects that produce the flux of ...
