An analysis is performed of the spectrum of gamma rays from the Crab Nebula in the 4–100 TeV range of energies, obtained using data from two Atmospheric Cherenkov Telescopes that are part of the TAIGA complex. A way of selecting and restoring the energy of gamma rays is described that ...
The CAT imaging telescope, recently built on the site of the former solar plant Themis (French Pyrenees), observed gamma-rays from the Crab nebula from October 1996 to March 1997. This steady source, often considered as the standard candle of very-high-energy gamma-ray astronomy, is used as...
A joint research team made up of Chinese and Japanese scientists has discovered the highest energy cosmic gamma rays ever observed from an observatory in Tibet, opening a new window to explore the extreme universe.The energy of the gamma rays is as high as 450 TeV, equivalent to 45 billion ...

BEIJING, July 3 (Xinhua) -- A joint research team made up of Chinese and Japanese scientists has discovered the highest energy cosmic gamma rays ever observed from an observatory in Tibet, opening a new window to explore the extreme universe. The energy of the gamma rays is as high as 450...
differential energy spectrum is represented by the power law J r ( E )= 129·4 E 2·62±0·12 photons m 2 sr 1 sec 1 GeV 1 at an effective atmospheric depth of 14·3 g cm 2 ; this is the first reliable balloon measurement of atmospheric gamma rays in the energy range 40–1000...
Indeed, the radiation field at the CERF is mostly made of neutrons and gamma rays, with neutrons spanning over a wide energy range from thermal to the beam energy, and gamma rays from about 100 keV. The CERF features also a relevant contribution of electrons and positrons from about 1 MeV...
The observation of the energy spectra of γ-rays and hadrons with energy greater than 2 TeV was carried out at Mt. Fuji (3776 m above sea-level, 650 g·cm 2 atmospheric depth) with a thick Fe emulsion chamber. The results show that there is an appreciable difference between the indices...
