A new method to measure the attenuation of hadrons in extensive air showers
W. D. Apel
Extensive air showers are generated through interactions of high-energy cosmic rays impinging the Earth's atmosphere. A new method is described to infer the attenuation of hadrons…
Active Galactic Nuclei: Sources for ultra high energy cosmic rays?
P. L. Biermann, J. K. Becker, L. Caramete +11
The origin of ultra high energy cosmic rays promises to lead us to a deeper understanding of the structure of matter. This is possible through the study of particle collisions at c…
Frequency spectra of cosmic ray air shower radio emission measured with LOPES
A. Nigl
AIMS: We wish to study the spectral dependence of the radio emission from cosmic-ray air showers around 100 PeV (1017 eV). METHODS: We observe short radio pulses in a broad frequen…
Direction identification in radio images of cosmic-ray air showers detected with LOPES and KASCADE
A. Nigl
AIMS: We want to understand the emission mechanism of radio emission from air showers to determine the origin of high-energy cosmic rays. Therefore, we study the geometry of the ai…
