Cosmic γ rays and cosmic-ray particles

Nature, 1983
Recent experiments using extensive air shower techniques1–5 have given evidence for the presence of significant fluxes of cosmic γ rays, in the energy range 1015–1016 eV, from specific cosmic sources. We argue here that the flux from these sources, and others as yet unresolved, is probably sufficient to allow the explanation of a number of previously ...

Cosmic-ray astrochemistry

Chemical Society Reviews, 2013
Gas-phase chemistry in the interstellar medium is driven by fast ion-molecule reactions. This, of course, demands a mechanism for ionization, and cosmic rays are the ideal candidate as they can operate throughout the majority of both diffuse and dense interstellar clouds.

Cosmic-ray Clocks

Space Science Reviews, 1998
Secondary radioactive isotopes that are used for the determination of cosmic-ray age have relatively short decay lifetimes. The measured abundance of these isotopes at low energies is representative of the cosmic-ray diffusion and the gas distribution in a region of a few hundred parsecs around the Sun.
