Solar Neutron Event in Association with a Large Solar Flare on November 24, 2000

K. Watanabe, Y. Muraki, Y. Matsubara +15

Solar neutrons have been detected using the neutron monitor located at Mt. Chacaltaya, Bolivia, in association with a large solar flare on November 24, 2000. This is the first dete…

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…

Small-scale anisotropy of cosmic rays above 10^19eV observed with the Akeno Giant Air Shower Array

M. Takeda, N. Hayashida, K. Honda +25

With the Akeno Giant Air Shower Array (AGASA), 581 cosmic rays above 10^19eV, 47 above 4 x 10^19eV, and 7 above 10^20eV are observed until August 1998. Arrival direction distributi…

TeV gamma-ray observations of southern BL Lacs with the CANGAROO 3.8m Imaging Telescope

M. D. Roberts, S. A. Dazeley, P. G. Edwards +32

Observational and theoretical results indicate that low-redshift BL Lacertae objects are the most likely extragalactic sources to be detectable at TeV energies. In this paper we pr…

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…
