On a possible photon origin of the most-energetic AGASA events
P. Homola, M. Risse, R. Engel +5
In this work the ultra high energy cosmic ray events recorded by the AGASA experiment are analysed. With detailed simulations of the extensive air showers initiated by photons, the…
Primary Proton Spectrum of Cosmic Rays measured with Single Hadrons
T. Antoni, KASCADE Collaboration
The flux of cosmic-ray induced single hadrons near sea level has been measured with the large hadron calorimeter of the KASCADE experiment. The measurement corroborates former resu…
Impact of Varying Atmospheric Profiles on Extensive Air Shower Observation: - Atmospheric Density and Primary Mass Reconstruction -
B. Keilhauer, J. Bluemer, R. Engel +2
The longitudinal profile of extensive air showers is sensitive to the energy and type/mass of the primary particle. One of its characteristics, the atmospheric depth of shower maxi…
Sources of Cosmic Rays and Galactic Diffuse Gamma Radiation
Sabrina Casanova, Peter L. Biermann, Ralph Engel +2
The diffuse galactic gamma-ray spectrum measured by the EGRET experiment \citep{Hunter:1997} are interpreted within a scenario in which cosmic rays (CRs) are injected by three diff…
The last Gamma Ray Burst in our Galaxy? On the observed cosmic ray excess at particle energy 1 EeV
Peter L. Biermann, Gustavo Medina-Tanco, Ralph Engel +1
Here we propose that the excess flux of particle events of energy near 1 EeV from the direction of the Galactic Center region is due to the production of cosmic rays by the last fe…
