Observation of PeV Gamma Rays from the Monogem Ring with the Tibet Air Shower Array

The Tibet AS Gamma Collaboration, M. Amenomori

We searched for steady PeV gamma-ray emission from the Monogem ring region with the Tibet air shower array from 1997 February to 2004 October. No evidence for statistically signifi…

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

The Tibet AS Gamma Collaboration, M. Amenomori

A hybrid experiment consisting of emulsion chambers, burst detectors and the Tibet II air-shower array was carried out at Yangbajing (4,300 m a.s.l., 606 g/cm) in Tibet to obta…

A study of the shadowing of galactic cosmic rays by the sun in a quiet phase of solar activity with the Tibet air shower array

M. Amenomori, S. Ayabe, Caidong

We have shown that the Sun's shadow by high energy cosmic rays moves year by year and its behavior is correlated with a time variation of the large-scale structure of the solar and…
