Origin of cosmic rays [PDF]

Astroparticle Physics, 2012
It is argued that there are three `origins' of cosmic rays; the origin of the particles, the origin of the energy, and the site of the acceleration. The evidence for each origin is discussed and a plausible synthesis outlined for the particles of Galactic origin where the energy comes mainly (but not exclusively) from supernova explosions, the site of ...

The Impact of Cosmic-Ray Transport on the Gamma-Ray Luminosity of Diffuse Gas

The Astrophysical Journal
In astrophysical media, relativistic particles (cosmic rays) collide with thermal particles and produce γ -rays through pion decay. Therefore, observations of γ -rays from diffuse gas provide an opportunity to study the distribution of cosmic rays in ...

The AMS-02 Cosmic-Ray Deuteron Flux is Consistent with a Secondary Origin

The Astrophysical Journal Letters
The recent measurements of cosmic-ray (CR) deuteron fluxes by AMS-02 show that the rigidity dependence of deuterons is similar with that of protons but flatter than ^3 He, which has been attributed to the existence of primary deuterons with abundance ...

Study of Flat-spectrum Radio Quasars and BL Lacertae Objects as Sources of Diffusive Ultrahigh-energy Cosmic Rays

The Astrophysical Journal
We examine whether flat-spectrum radio quasars (FSRQs) and BL Lac objects can act as plausible astrophysical sources of diffuse ultrahigh-energy cosmic rays (UHECRs).

A Cosmic Ray Acceleration Mechanism Based on Background Flow Velocity Inhomogeneities Yielding Power-law Spectra

The Astrophysical Journal
In astrophysics, one significant challenge lies in understanding the acceleration of cosmic rays, which leads to the occurrence of a power law. In this article, momentum transport generated by the combined effects of pitch-angle diffusion and background ...
