Opening a New Astronomy through Charged
ParticlesῌObservation of the Ultra-High
Energy Cosmic Rays by the Pierre Auger
Observatory
Tokonatsu YAMAMOTO
Faculty of Science and Engineering, Konan
University, 8῍9῍1 Okamoto, Higashinada-ku, Kobe,
Hyogo 658῍8501, Japan
Abstract : The highest energy particles in the
Universe are called Ultra-High-Energy Cosmic
Rays (UHECRs). These particles should bring
enormous information of the high-energy
phenomenon in the Universe.
To reveal
mysteries of the UHECRs, the Pierre Auger
observatory has been constructed. Recent results
from this project indicate the arrival direction of
the UHECR correlates to the direction of the
Active Galactic Nucleus. In this report, we
describe this observatory and discuss new image
of the Universe through UHECRs.
