Analysis of Radio measurements at the Pierre Auger Observatory — •Nunzia Palmieri — Universitaet Karlsruhe, IEKP

Cosmic Rays are high-energy particles coming from space that strike the Earth from all directions. In the interactions of energetic CRs with the atoms of the atmosphere a large number of secondary particles is generated, creating the so-called Extensive Air Showers (EAS).
One of the largest experiments for measuring EAS is the southern Pierre Auger Observatory (PAO) in which two different detection techniques, the Surface Particle Detectors and the Fluorescence Detectors are employed. A third technique which can complement the existing detection methods is the Radio Detection of pulsed radio signals emitted by EAS.
The application of the Radio Detection technique on large scales is currently being developed in the framework of the Pierre Auger Observatory. An analysis of Radio data gathered in the PAO with a prototype antenna array will be presented. Various aspects are taken into account and, in particular, a detailed analysis of polarization measurements has been performed.
