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…
Doppler Boosting, Superluminal Motion, and the Kinematics of AGN Jets
K. I. Kellermann, Y. Y. Kovalev, M. L. Lister +8
We discuss results from a decade long program to study the fine-scale structure and the kinematics of relativistic AGN jets with the aim of better understanding the acceleration an…
Kinematic Study of the Blazar 0716+714
U. Bach, T. P. Krichbaum, S. Britzen +3
We determined the kinematics at the jet of 0716+714 from a reanalysis of multi-frequency VLBI data (5, 8.4, 15, 22 GHz) obtained during the last 10 years combined with data from th…
