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…
Geometry reconstruction of fluorescence detectors revisited
D. Kuempel, K. -H. Kampert, M. Risse
The experimental technique of fluorescence light observation is used in current and planned air shower experiments that aim at understanding the origin of ultra-high energy cosmic…
Detection of Atmospheric Muon Neutrinos with the IceCube 9-String Detector
The IceCube Collaboration, A. Achterberg
The IceCube neutrino detector is a cubic kilometer TeV to PeV neutrino detector under construction at the geographic South Pole. The dominant population of neutrinos detected in Ic…
Five years of searches for point sources of astrophysical neutrinos with the AMANDA-II neutrino telescope
A. Achterberg
We report the results of a five-year survey of the northern sky to search for point sources of high energy neutrinos. The search was performed on the data collected with the AMANDA…
