A comparison of the cosmic-ray energy scales of Tunka-133 and KASCADE-Grande via their radio extensions Tunka-Rex and LOPES
W. D. Apel, J. C. Arteaga-Velázquez, L. Bähren +73
The radio technique is a promising method for detection of cosmic-ray air showers of energies around PeV and higher with an array of radio antennas. Since the amplitude of t…
Calibrating the absolute amplitude scale for air showers measured at LOFAR
A. Nelles, J. R. Hörandel, T. Karskens +74
Air showers induced by cosmic rays create nanosecond pulses detectable at radio frequencies. These pulses have been measured successfully in the past few years at the LOw Frequency…
Detecting cosmic rays with the LOFAR radio telescope
P. Schellart, A. Nelles, S. Buitink +102
The low frequency array (LOFAR), is the first radio telescope designed with the capability to measure radio emission from cosmic-ray induced air showers in parallel with interferom…
Mass sensitivity in the radio lateral distribution function
W. D. Apel, J. C. Arteaga, L. Bähren +56
Measuring the mass composition of ultra-high energy cosmic rays is one of the main tasks in the cosmic rays field. Here we are exploring the composition signature in the coherent e…
LOPES-3D, an antenna array for full signal detection of air-shower radio emission
W. D. Apel, J. C. Arteaga, L. Bähren +56
To better understand the radio signal emitted by extensive air-showers and to further develop the radio detection technique of high-energy cosmic rays, the LOPES experiment was rec…
Experimental evidence for the sensitivity of the air-shower radio signal to the longitudinal shower development
W. D. Apel, J. C. Arteaga, L. Bähren +56
We observe a correlation between the slope of radio lateral distributions, and the mean muon pseudorapidity of 59 individual cosmic-ray-air-shower events. The radio lateral distrib…
Observing pulsars and fast transients with LOFAR
B. W. Stappers, J. W. T. Hessels, A. Alexov +91
Low frequency radio waves, while challenging to observe, are a rich source of information about pulsars. The LOw Frequency ARray (LOFAR) is a new radio interferometer operating in…
On noise treatment in radio measurements of cosmic ray air showers
F. G. Schröder, W. D. Apel, J. C. Arteaga +58
Precise measurements of the radio emission by cosmic ray air showers require an adequate treatment of noise. Unlike to usual experiments in particle physics, where noise always add…
Air Shower Measurements with LOFAR
A. Horneffer, L. Bähren, S. Buitink +7
Air showers from cosmic rays emit short, intense radio pulses. LOFAR is a new radio telescope, that is being built in the Netherlands and Europe. Designed primarily as a radio inte…
