Updated AGASA event list above 4x10^19eV
N. Hayashida, K. Honda, N. Inoue +26
After our Ap.J. publication of the Akeno Giant Air Shower Array (AGASA) results in 1999 (Takeda et al., 1999), we observed nine events with energies above 4 10eV un…
The Anisotropy of Cosmic Ray Arrival Direction around 10^18eV
N. Hayashida, K. Honda, N. Inoue +29
Anisotropy in the arrival directions of cosmic rays around 10^{18}eV is studied using data from the Akeno 20 km^2 array and the Akeno Giant Air Shower Array (AGASA), using a total…
Extension of the Cosmic-Ray Energy Spectrum Beyond the Predicted Greisen-Zatsepin-Kuz'min Cutoff
M. Takeda, N. Hayashida, K. Honda +25
The cosmic-ray energy spectrum above 10^{18.5} eV is reported using the updated data set of the Akeno Giant Air Shower Array (AGASA) from February 1990 to October 1997. The energy…
The Anisotropy of Cosmic Ray Arrival Directions around 10eV
AGASA Collaboration, N. Hayashida, K. Honda +26
Anisotropy in the arrival directions of cosmic rays with energies above 10eV is studied using data from the Akeno 20 km array and the Akeno Giant Air Shower Array (AGASA…
Observations of TeV gamma ray flares from Markarian 501 with the Telescope Array Prototype
Telescope Array Collaboration
We will report the observations of TeV gamma ray flares from Markarian 501 using Telescope Array Prototype. The observation were carried out continuously from the end of March to t…
