Ultra high energy cosmic rays and ultra high energy γ-rays

Advances in Space Research, 1984
Abstract Evidence on the energy spectrum, mass composition and anisotropy of cosmic rays above 10 14 eV is briefly surveyed and it is shown that the data are consistent with all cosmic rays below 10 19 eV being of galactic origin. Results from the new field of γ-ray astronomy above 10 15 eV are described and implications for the origin of cosmic ...

Ultra High Energy Cosmic Rays

1983
The interpretation of observations on cosmic rays above 1015 eV is discussed in simple terms, without considering detailed models. The variation of the amplitude of anisotropy with energy (compared with a “leaky box” picture) and the anisotropy in galactic latitude (indicating a local density gradient) strongly suggest a galactic origin for particles ...

Ultra high energy cosmic ray (present)

Nuclear Physics B - Proceedings Supplements, 2002
Abstract The existence of Super-GZK particles, cosmic rays above 10 20 eV , was well established by the AGASA experiment. Recent data from AGASA strongly suggests the existence of compact sources, event clusters. These two experimental evidences seem to be contradictory each other and are difficult to be explained by the simple theoretical models ...

Ultra high energy cosmic ray horizons

Nuclear Physics B - Proceedings Supplements, 2009
We calculate the horizons of ultra high energy cosmic rays assuming different primary nuclei ranging from proton to iron at ultra high energies ( 6 ⋅ 10 19 eV ). We show that sources of ultra high energy protons and heavy nuclei can originate from distances up to ∼ 180 Mpc , while low and intermediate mass nuclei can only originate
