| 英文摘要 | Kascade and kascade-grande were multi-detector installations to measure individual air showers of cosmic rays at ultra-high energy. based on data sets measured by kascade and kascade-grande, 90% c.l. upper limits to the flux of gamma-rays in the primary cosmic ray flux are determined in an energy range of 10(14)-10(18) ev. the analysis is performed by selecting air showers with a low muon content as expected for gamma-ray-induced showers compared to air showers induced by energetic nuclei. the best upper limit of the fraction of gamma-rays to the total cosmic ray flux is obtained at 3.7 x 10(15) ev with 1.1 x 10(-5). translated to an absolute gamma-ray flux this sets constraints on some fundamental astrophysical models, such as the distance of sources for at least one of the icecube neutrino excess models. |
