Fluorescence in damp air and comments on the radiative life time
N. Sakaki, K. Kobayakawa, M. Nagano +1
Photon yields in damp air excited by an electron using a Sr90 source are compared withthose in dry air. Water vapors considerably reduce the yields, however, a further study is…
Photon yields from nitrogen gas and dry air excited by electrons
M. Nagano, K. Kobayakawa, N. Sakaki +1
In order to detect ultrahigh-energy cosmic rays (UHECR), atmospheric fluorescence light from the trajectory of the extensive air shower may be measured by mirror-photosensor system…
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…
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…
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…
