Sources of sub-GZK cosmic rays [PDF]

, 2002
We analyze the existing evidence that BL Lacertae objects (BL Lacs) are sources of the highest-energy cosmic rays. We argue that three independent signatures observed in the real data -- (1) improvement of correlations with corrections of trajectories ...

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

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 ...

SAS-2 observations of the galactic gamma radiation from the Vela region [PDF]

Data from a scan of the galactic plane by the SAS-2 high energy gamma ray experiment in the region 250 deg l2 290 deg show a statistically-significant excess over the general radiation from the galactic plane for gamma radiation of energy 100 MeV in ...

Angular Power Spectrum of TeV–PeV Cosmic-Ray Anisotropies

The Astrophysical Journal
Simulations of the cosmic-ray (CR) anisotropy down to TeV energies are presented, using turbulence parameters consistent with those inferred from observations of the interstellar medium.

Observing the Energetic Universe at Very High Energies with the VERITAS Gamma Ray Observatory

, 2018
Very high energy gamma-ray observations offer indirect methods for studying the highest energy cosmic rays in our Universe. The origin of cosmic rays at energies greater than $10^{18}$ eV remains a mystery, and many questions in particle astrophysics ...
