Radio detection of cosmic ray air showers with lopes
(Academiei RomaneBucharest, 2012)
Cosmic ray air showers are high energetic particles coming from the Universe toward the Earth every second. It is well known that they generate electromagnetic waves in the Earth atmosphere detectable on the ground. LOPES ...
Muon production height studies with the air shower experiment KASCADE-Grande
(Elsevier BVAmsterdam, 2011-01)
A large area (128 m2) muon tracking detector, located within the KASCADE experiment, has been built with the aim to identify muons (Eμ > 0.8 GeV) and their angular correlation in extensive air showers by track measurements ...
The wavefront of the radio signal emitted by cosmic ray air showers
(Institute of Physics - IOPBristol, 2014-09)
Analyzing measurements of the LOPES antenna array together with corresponding CoREAS simulations for more than 300 measured events with energy above '10 POT. 17' eV and zenith angles smaller than 45◦, we find that the radio ...
A study of the effect of molecular and aerosol conditions in the atmosphere on air fluorescence measurements at the Pierre Auger Observatory
(Elsevier ScienceAmsterdam, 2010-03)
The air fluorescence detector of the Pierre Auger Observatory is designed to perform calorimetric measurements of extensive air showers created by cosmic rays of above View the MathML source. To correct these measurements ...
A new observable in extensive air showers
(Elsevier Science, 2016-12)
We find that the ratio rμe of the muon to the electromagnetic component of an extended air shower at the ground level provides an indirect measure of the depth Xmax of the shower maximum. This result, obtained with the ...
Properties of ultraviolet light in extensive air showers
(Iop Publishing LtdBristolInglaterra, 2000)
Thunderstorm observations by air-shower radio antenna arrays
Relativistic, charged particles present in extensive air showers (EAS) lead to a coherent emission of radio pulses which are measured to identify the shower initiating high-energy cosmic rays. Especially during thunderstorms, ...
Detection of a change of slope in the spectrum of heavy mass cosmic rays primaries by the Kascade-Grande experiment
(Ceske Vysoke Uceni TechnickePrague, 2013)
KASCADE-Grande is an extensive air shower experiment devoted to the study of cosmic rays in the '10 POT. 16' ÷ '10 POT. 18' eV energy range. The array comprises various detectors allowing independent measurements of the ...
Photoproduction total cross section and shower development
(American Physical Society, 2015-12)
The total photoproduction cross section at ultrahigh energies is obtained using a model based on QCD minijets and soft-gluon resummation and the ansatz that infrared gluons limit the rise of total cross sections. This cross ...
