First Detection of sub-PeV Diffuse Gamma Rays from the Galactic Disk: Evidence for Ubiquitous Galactic Cosmic Rays beyond PeV Energies. [PDF]

Physical Review Letters, 2021
We report, for the first time, the long-awaited detection of diffuse gamma rays with energies between 100 TeV and 1 PeV in the Galactic disk. Particularly, all gamma rays above 398 TeV are observed apart from known TeV gamma-ray sources and compatible ...

The Origin of Galactic Cosmic Rays as Revealed by their Composition [PDF]

International Conference on Rebooting Computing, 2021
Galactic cosmic-rays (GCRs) are thought to be accelerated in strong shocks induced by massive star winds and supernova explosions sweeping across the interstellar medium.

Red Dwarfs as Sources of Cosmic Rays [PDF]

EPJ 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

Universe, 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

The origin of Galactic cosmic rays: Challenges to the standard paradigm [PDF]

International Journal of Modern Physics D, 2019
A critical review of the standard paradigm for the origin of Galactic cosmic rays (CRs) is presented. Recent measurements of local and far-away CRs reveal unexpected behaviors, which challenge the commonly accepted scenario.

SOLAR ACTIVITY AND EARTH SEISMICITY

Solar-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.

Probing the sea of galactic cosmic rays with Fermi-LAT [PDF]

Physical Review D, 2018
High energy $\ensuremath{\gamma}$-rays from giant molecular clouds (GMCs) carry direct information about the spatial and energy distributions of galactic cosmic rays (CRs).

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

EPJ 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.

Solar energetic particles and galactic cosmic rays over millions of years as inferred from data on cosmogenic 26Al in lunar samples [PDF]

Astronomy & Astrophysics, 2018
Aims. Lunar soil and rocks are not protected by a magnetic field or an atmosphere and are continuously irradiated by energetic particles that can produce cosmogenic radioisotopes directly inside rocks at different depths depending on the particle’s ...
