10. Recent results of the Pierre Auger Observatory

Dr Alexandre Creusot (University of Nova Gorica)

oral presentation

The Pierre Auger Observatory measures extensive air showers induced by ultra high energy cosmic rays using a hybrid detector (fluorescence and surface detector). The Pierre Auger Observatory has been designed for a high statistics, full sky study of cosmic rays at the highest energies. Energy, arrival direction and mass composition measurements are investigated in order to illuminate the...

51. Limits on the diffuse flux of ultra-high energy neutrinos using the Pierre Auger Observatory

oral presentation

The surface detector array of the Pierre Auger Observatory is sensitive to ultra-high energy neutrinos in the cosmic radiation, These particles can interact close to ground, both through charged and neutral currents in the atmosphere (down-going) and, for tau neutrinos, through the ”Earth skimming” mechanism (up-going) where a tau lepton is produced in the Earth’s curst that can emerge and...

30. Microwave detection of air showers with MIDAS

Microwave emission due to molecular bremsstrahlung in the free electron collisions with the neutral molecules in the atmosphere (within the plasma produced by the cascade ionization) could be used to detect extensive air showers. Measurements show that molecular bremsstrahlung scales quadratically with the primary energy and is isotropic and unpolarized, and thus it could be used to...

42. Radio Detection of Cosmic-Ray-Induced Air Showers at the Pierre Auger Observatory

Stefan Fliescher (RWTH Aachen University)

oral presentation

AERA --- the Auger Engineering Radio Array --- is currently being set up at the southern site of the Pierre Auger Observatory. AERA will explore the potential of the radio detection technique to cosmic ray induced air showers with respect to the next generation of large-scale surface detectors. As AERA is co-located with the low energy enhancements of the Pierre Auger Observatory, the...

48. Results from polarization studies of radio signals induced by cosmic rays at the Pierre Auger Observatory

Harm Schoorlemmer (Radboud university nijmegen)

At the Pierre Auger Observatory, the radio emission from cosmic-ray-induced air showers is measured. I will discuss the physics results from a setup consisting of three antennas triggered by an auxiliary particle detector. With this setup, a total 494 events were registered in coincidence with the surface detector of the Pierre Auger Observatory. This data allows us to study the dependence of...

57. Self-triggered detection of cosmic ray air showers at Auger with the RAuger experiment.

Benoit Revenu (SUBATECH, Nantes)

oral presentation

RAuger is a self-triggered and fully autonomous cosmic ray radio detection experiment installed at the Surface Detector (SD) of the Pierre Auger Observatory. Operating since July 2007, we have obtained more than 60 coincidences with Auger leading to a skymap (azimuth, zenith) showing evidence for a geomagnetic effect in the electric field emission mechanism. We also have obtained a three-fold...
