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.

Active Galactic Nuclei with Starbursts: Sources for Ultra High Energy Cosmic Rays [PDF]

open access: yes, 2009
Ultra high energy cosmic ray events presently show a spectrum, which we interpret here as galactic cosmic rays due to a starburst in the radio galaxy Cen A pushed up in energy by the shock of a relativistic jet.

The origin of galactic cosmic rays [PDF]

open access: yes, 2007
The origin of galactic cosmic rays is one of the most interesting unsolved problems in astroparticle physics. Experimentally, the problem is attacked by a multi-disciplinary effort, namely by direct measurements of cosmic rays above the atmosphere, by ...

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 ...

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 ...
