The energy spectrum of all - particle cosmic rays around the knee region observed with the Tibet - III air - shower array
We have already reported the first result on the all-particle spectrum around the knee region based on data from 2000 November to 2001 October observed by the Tibet-III air-shower array. In this paper, we present an updated result using data set collected in the period from 2000 November through 2004 October in a wide range over 3 decades between 1014 eV and 1017 eV, in which the position of th...
متن کاملCosmic rays observed by the resonant gravitational wave detector NAUTILUS
The passage of cosmic rays has been observed to excite mechanical vibrations in the resonant gravitational wave detector NAUTILUS operating at temperature of 100 mK. A very significant correlation (more than 10 standard deviations) is found.
متن کاملDetailed analysis of observed antiprotons in cosmic rays
In the present work, the origin of antiprotons observed in cosmic rays (above the atmosphere) is analyzed in details. We have considered the origin of the primaries, (which their interactions with the interstellar medium is one of the most important sources of antiprotons) is a supernova type II then used a diffusion model for their propagation. We have used the latest parameterization for anti...
متن کاملThe Chemical Composition of Cosmic Rays
A brief review about the chemical composition of cosmic rays in the energy range 10 <∼ E <∼ 10 20 eV is given. While there is convincing evidence for an increasingly heavier composition above the knee, no clear picture has emerged at the highest energies, yet. We discuss implications about the origin of cosmic rays and emphasize systematic differences related to data analysis techniques and to ...
متن کاملElemental Composition of Cosmic Rays near the Knee by Multiparameter Measurements of Air Showers
The small change in the spectral slope of the overall intensity of cosmic rays near 1 PeV may be associated with the endpoint energy of supernova shock acceleration. A crucial test of this connection and other ideas of the origin of the spectral ‘knee’ is the reliable determination of the variation of elemental composition in this region. Recent measurements at the DICE/CASA/MIA air shower inst...
