Search for Galactic cosmic ray sources: The multimessenger approach

EPJ Web of Conferences, 2015
The search for the sources of high-energy cosmic rays (CRs) has made significant progress the past decade. By including multimessenger methods, the general picture of the presence of a Galactic component at low energies and an extragalactic one at the ...

The generation of low-energy cosmic rays in molecular clouds

, 2005
It is argued that if cosmic rays penetrate into molecular clouds, the total energy they lose can exceed the energy from galactic supernovae shocks. It is shown that most likely galactic cosmic rays interacting with the surface layers of molecular clouds ...

Spectra of He Isotopes and the 3He/4He Ratio

The Astrophysical Journal
Since its launch, the Alpha Magnetic Spectrometer-02 (AMS-02) has delivered outstanding quality measurements of the spectra of cosmic-ray (CR) species, e ^± , $\bar{p}$ , and nuclei (H–Si, S, Fe), which have resulted in a number of breakthroughs. Besides

Galactic Anisotropy as Signature of ``Top-Down'' Mechanisms of Ultra-High Energy Cosmic Rays

, 1998
We show that ``top-down'' mechanisms of Ultra-High Energy Cosmic Rays which involve heavy relic particle-like objects predict Galactic anisotropy of highest energy cosmic rays at the level of minimum $\sim 20%$.

Isotopes in Galactic Cosmic Rays [PDF]

Symposium - International Astronomical Union, 1981
The data on isotopic ratios of elements in Galactic Cosmic Rays (GCR) is steadily improving and has recently reached the point where some information can be extracted, which has bearing on the problem of the origin of the cosmic rays. By and large, these data have generally confirmed the similarity between solar-type matter and GCR source, when ...
