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…
Energy Spectra of Elemental Groups of Cosmic Rays: Update on the KASCADE Unfolding Analysis
KASCADE Collaboration, W. D. Apel
The KASCADE experiment measures extensive air showers induced by cosmic rays in the energy range around the so-called knee. The data of KASCADE have been used in a composition anal…
Air Shower Measurements with the LOPES Radio Antenna Array
A. Haungs
LOPES is set up at the location of the KASCADE-Grande extensive air shower experiment in Karlsruhe, Germany and aims to measure and investigate radio pulses from Extensive Air Show…
Amplitude calibration of a digital radio antenna array for measuring cosmic ray air showers
S. Nehls, A. Hakenjos, M. J. Arts +9
Radio pulses are emitted during the development of air showers, where air showers are generated by ultra-high energy cosmic rays entering the Earth's atmosphere. These nanosecond s…
Origin and physics of the highest energy cosmic rays: What can we learn from Radio Astronomy?
Peter L. Biermann, P. Gina Isar, Ioana C. Maris +2
Here in this lecture we will touch on two aspects, one the new radio methods to observe the effects of high energy particles, and second the role that radio galaxies play in helpin…
Radio Emission in Atmospheric Air Showers: First Measurements with LOPES-30
P. G. Isar, S. Nehls, LOPES Collaboration
When Ultra High Energy Cosmic Rays interact with particles in the Earth's atmosphere, they produce a shower of secondary particles propagating toward the ground. LOPES-30 is an abs…
Variable Very High Energy Gamma-ray Emission from the Microquasar LS I +61 303
MAGIC Collaboration, J. Albert
Microquasars are binary star systems with relativistic radio-emitting jets. They are potential sources of cosmic rays and laboratories for elucidating the physics of relativistic j…
Observation of VHE Gamma Radiation from HESS J1834-087/W41 with the MAGIC Telescope
J. Albert et al.
Recently, the HESS array has reported the detection of gamma-ray emission above a few hundred GeV from eight new sources located close to the Galactic Plane. The source HESS J1834-…
