Cosmic rays are charged particles arriving at the Earth from space. Those at the highest energies are particularly interesting because the physical processes that could create or …

Cosmic rays are atomic nuclei arriving from outer space that reach the highest energies observed in nature. Clues to their origin come from studying the distribution of their arrival …
In this Letter we examine the arrival directions of the most energetic cosmic rays (E> 2× 10 19 eV) detected by several air shower experiments. We find that data taken by different air …
The origin of cosmic rays is one of the major unresolved questions in astrophysics. In particular, the highest energy cosmic rays observed have macroscopic energies up to …

The authors define “ultrahigh-energy cosmic rays”(UHECRs) as those cosmic rays with energies above 10 18 eV. It had been anticipated that there would be a cutoff in the energy …

We measure the spectrum of cosmic rays with energies greater than 10 18.2 eV with the fluorescence detectors (FDs) and the surface detectors (SDs) of the Telescope Array …
The ultra—high energy cosmic rays recently detected by several air shower experiments could have an extragalactic origin. In this case, the nearest active galaxy Centaurus A might …

The existence of extremely high energy cosmic rays (EHECRs) with energies exceeding 1020 eV has been reported by the AGASA experiment. These cosmic rays may be produced …

We present numerical simulations for energy spectra and angular distributions of nucleons above 10 19 eV injected by the radio-galaxy Centaurus A at a distance 3.4 Mpc and …
