During a period of about two years, a total of 24 gamma-ray photons above 100 TeV have been detected from the Crab Nebula, as a result of the innovative upgrading of the experiment, according to Huang."This is a significant first step forward. It proves that our techniques worked well, ...
Bepp SAX answered the first question, and now the location, the distance and the energetic of Gamma-Ray Bursts is no more a mystery. Thanks to the wealth of data now available the answer to the second one is likely in the way. The status of the knowledge and the major open points ...

and covering an area of 1.36 square kilometers, LHAASO is used to conduct cosmic ray observation and research. It is the most sensitive ultra-high-energy gamma-ray detection device in the world, with a large field of view and all-weather monitoring capability, covering two-thirds of the ...
Extensive air shower data collected using the CASA-MIA detector are examined for evidence of gamma rays above 50 TeV from the directions of 32 active galactic nuclei. Gamma rays above 100 MeV from all of these objects have been detected previously by the Energetic Gamma Ray Experiment Telescope ...
Gamma-ray bursts (GRBs) are brief flashes of γ-rays and are considered to be the most energetic explosive phenomena in the Universe. The emission from GRBs comprises a short (typically tens of seconds) and bright prompt emission, followed by a much longer afterglow phase. During the ...
Very high energy gamma-rays can be used to probe some of the most powerful astrophysical objects in the universe, such as active galactic nuclei, supernova... AA Abdo 被引量: 11发表: 2007年 Discovery of localized TeV gamma -ray sources and diffuse TeV gamma -ray emission from the galactic...
in its turn is absorbed and reemitted. as the energy filters through the layers of the solar interior, it passes through the -ray part of the spectrum eventually becoming light. at this stage, it has reached what we call the solar surface, and can escape into space without being absorbed...
