High-speed-photon detectors are some of the most important tools for observations of high energy cosmic rays. As technologies of photon detectors and their read-out electronics improved rapidly, the time resolution of some cosmic ray detectors became

Study of the arrival direction distribution plays a key role in finding sources of the Extremely High Energy Cosmic Rays (EHECR). Greisen-Zatsepin-Kuz'min (GZK) mechanism limits the propagation of EHE cosmic rays significantly and only nearby sources

Using data from more than ten-years of observations with the Akeno Giant Air Shower Array (AGASA), we published that the energy spectrum of ultra-high energy cosmic rays extends beyond the GZK cutoff. We have reevaluated the energy determination meth

We have observed ultra-high energy cosmic rays above the Greisen-Zatsepin-Kuz'min cut-off energy by Akeno Giant Air Shower Array. Their chemical composition is a key discriminator of origin models. In the present work, we estimate the average composi

The origin of the highest energy cosmic rays (−1020 eV) is not well understood. Interesting models called ^top-down ̄ scenarios have been proposed to explain the origin. The g-ray flux in ultra?high-energy cosmic rays is a key parameter for givi
