Journal ArticleDOI

Anisotropy and corotation of galactic cosmic rays.

TL;DR: Two-dimensional high-precision anisotropy measurement for energies from a few to several hundred teraelectronvolts (TeV) is presented, using the large data sample of the Tibet Air Shower Arrays, revealing finer details of the known anisotropies.
Journal ArticleDOI

The All-Particle Spectrum of Primary Cosmic Rays in the Wide Energy Range from 1014 to 1017 eV Observed with the Tibet-III Air-Shower Array

TL;DR: In this paper, the authors presented an updated all-particle energy spectrum of primary cosmic rays in a wide range from 10 14 to 10 17 eVusing 5:5 ; 10 7 events collected from 2000 November through 2004 October by the Tibet-III air-shower array located 4300 m in altitude.
Journal ArticleDOI

Large-Scale Sidereal Anisotropy of Galactic Cosmic-Ray Intensity Observed by the Tibet Air Shower Array

TL;DR: In this paper, the sidereal anisotropy of cosmic ray intensity in the multi-TeV region observed with the Tibet-III air shower array during the period from 1999 through 2003 was analyzed.
Journal ArticleDOI

Are protons still dominant at the knee of the cosmic-ray energy spectrum?

TL;DR: In this article, a hybrid experiment consisting of emulsion chambers, burst detectors and the Tibet-II air-shower array was carried out at Yangbajing (4300 m a.s.l., 606 g / cm 2 ) in Tibet to obtain the energy spectra of primary protons and heliums.
Journal ArticleDOI

A northern sky survey for steady tera-electron volt gamma-ray point sources using the tibet air shower array

TL;DR: In this paper, the results of a steady TeV γ-ray point-source search using data taken from the Tibet HD (1997 February-1999 September) and Tibet III (1999 November-2001 October) arrays are presented.
