The most energetic cosmic rays and their possible sources
L. G. Dedenko, D. A. Podgrudkov, T. M. Roganova +1
The primary cosmic rays particles with energies above 10**20 eV have been observed at many extensive air shower arrays since the beginning of observations over 40 years ago. The va…
The cosmic ray luminosity of the nearby active galactic nuclei
L. G. Dedenko, D. A. Podgrudkov, T. M. Roganova +1
The pointing directions of extensive air showers observed at the Pierre Auger Observatory were fitted within 3.1 degree with positions of the nearby active galactic nuclei from the…
The use of the Cherenkov radiation and the fluorescence light to calibrate the energy of giant air showers
L. G. Dedenko, D. A. Podgrudkov, T. M. Roganova +3
In terms of the quark-gluon string model the analysis of the classic procedure to estimate the energy of giant air showers with help of the parameter s(600) (a density of energy de…
Upper limit on the ultra-high-energy photon flux from AGASA and Yakutsk data
G. I. Rubtsov, L. G. Dedenko, G. F. Fedorova +8
We present the interpretation of the muon and scintillation signals of ultra-high-energy air showers observed by AGASA and Yakutsk extensive air shower array experiments. We consid…
