TL;DR: The Tibet air shower array has been in operation since January 1990 and searches for continual emission of 10-TeV gamma rays from the Crab Nebula, Cygnus X-3, and Hercules X-1 during the period from June 1990 through January 1992 find no dc excess.

TL;DR: The observed deflection of the Sun's shadow is briefly discussed in connection with the effect of the magnetic fields between the Sun and the Earth, the first observation of the effects of such magnetic fields on the cosmic-ray shadow.

TL;DR: The amplitude of the Compton-getting (CG) anisotropy contains the power-law index of the cosmic-ray energy spectrum as mentioned in this paper, which can be used to confirm the astrophysical origin of the "knee" against models for nonstandard hadronic interactions in the atmosphere.
Journal ArticleDOI
Intensity of protons at the “knee” of the cosmic ray spectrum
TL;DR: In this article, a detailed study on the simultaneous observation of air showers and high energy families has been done through a Monte Carlo simulation and the simulation results are compared with the experimental data obtained at Mt. Norikura to obtain for the first time the absolute flux values of primary protons at energies around 1015-1016 eV.
