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.

Measurement of Ultra-High Energy Cosmic Rays with CHICOS [PDF]
, 2009 The California HIgh school Cosmic ray ObServatory (CHICOS) is a ground-based scintillator array designed to measure the extended air showers of ultra-high energy cosmic rays. The goal of the project is to gain insight into the origin of ultra-high energy

The Revival of Galactic Cosmic‐Ray Nucleosynthesis? [PDF]
The Astrophysical Journal, 1999 Because of the roughly linear correlation between Be/H and Fe/H in low metallicity halo stars, it has been argued that a ``primary'' component in the nucleosynthesis of Be must be present in addition to the ``secondary'' component from standard Galactic cosmic ray nucleosynthesis.

Cosmic Ray Processes in Galactic Ecosystems
Galaxies, 2023 Galaxy evolution is an important topic, and our physical understanding must be complete to establish a correct picture. This includes a thorough treatment of feedback. The effects of thermal–mechanical and radiative feedback have been widely considered; however, cosmic rays (CRs) are also powerful energy carriers in galactic ecosystems.

Models for galactic cosmic-ray propagation [PDF]
Advances in Space Research, 2001 A new numerical model of particle propagation in the Galaxy has been developed, which allows the study of cosmic-ray and gamma-ray production and propagation in 2D or 3D, including a full reaction network. This is a further development of the code which has been used for studies of cosmic ray reacceleration, Galactic halo size, antiprotons and ...

New look on the origin of cosmic rays
EPJ 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 influence of galactic cosmic rays on ion-neutral hydrocarbon chemistry in the upper atmospheres of free-floating exoplanets [PDF]
, 2014 The authors highlight financial support of the European Community under the FP7 by an ERC starting grant.Cosmic rays may be linked to the formation of volatiles necessary for prebiotic chemistry.

Galactic cosmic ray modulation near the heliospheric current sheet [PDF]
, 2014 Galactic cosmic rays (GCRs) are modulated by the heliospheric magnetic field (HMF) both over decadal time scales (due to long-term, global HMF variations), and over time scales of a few hours (associated with solar wind structures such as coronal mass ...

COSMIC RAY PROPAGATION IN GALACTIC TURBULENCE [PDF]
The Astrophysical Journal, 2014 We revisit propagation of galactic cosmic rays (CRs) in light of recent advances in CR diffusion theory in realistic interstellar turbulence. We use a tested model of turbulence in which it has been shown that fast modes dominate scattering of CRs. As a result, propagation becomes inhomogeneous and environment dependent.
