High-redshift galaxies with strong star formation activity are likely sources of cosmic ray particles. At high-energies, these particles interact with the matter density and radiation fields of the galactic environment via hadronuclear, photo-pair and photo-pion processes to produce charged and neutral pions, neutrons and protons. The effect of these interactions is for the cosmic rays to deposit ... More

The comparison of computed galactic spectra with in situ experimental data at lower energies is possible with observations made by the Voyager 1 spacecraft outside the dominant modulating influence of the heliosphere. Galactic spectra computed by galactic propagation models and considered to be local interstellar spectra (LIS's), for specifically electrons, protons, Helium and Carbon nuclei, can n ... More

The origin of cosmic-ray (CR) PeVatrons is a long standing problem in the Astrophysics. The CR spectrum has a spectral break at about 1 PeV (so called, the knee energy). The diffusive shock acceleration at supernova remnants (SNRs) is believed to be the acceleration mechanism of CRs up to the knee energy. However, there are still many problems. One is the knee problem. It was estimated that SNRs c ... More

The Voyager 1 energy spectra of cosmic ray elements in the local interstellar medium (LISM) and models of interstellar propagation that fit these data and which also fit the data taken at 1 AU at high energies (Cummings et al., Astrophys. J., 2016) show a roll over from a power-law at high energies to a broad peak at lower energies. The break in the high-energy power law occurs at approximately 1 ... More

Spatial diffusion under the influence of the Galactic magnetic field (GMF) plays a crucial role in the transport of cosmic-ray protons. The standard assumption is that the GMF is purely azimuthal and the diffusion process can be considered to be uniform and isotropic all across the Galaxy. However, this picture might be inaccurate, since both theoretical arguments and numerical simulations predict ... More

Abstract content -- A hardening of the proton and helium fluxes is observed above a few hundreds of GeV/nuc. The actual distribution of the local sources of primary cosmic rays has been suggested as a potential solution to this puzzling behavior. Some authors even claim that a single source is responsible for the proton and helium anomalies. But how probable are such explanations ? To answer that ... More

Precise measurements of positron/electron ratio in the 1-500 GeV range have challenged the “standard” model of CR production in SNRs. After a brief decline between 2-8 GeV, the ratio rises steadily with a trend towards saturation around 200-400GeV. These observations appear to be in conflict with the diffusive shock acceleration (DSA) mechanism, operating in a single SNR shock. We argue that e ... More
