53. Measuring the spectrum of UHECR with the Pierre Auger Observatory

Dr Roberto Pesce (Università di Genova and INFN - Sezione di Genova)

The Pierre Auger Observatory is an experiment aimed at the detection of the Extensive Air Showers (EAS) produced by the Ultra-High Energy Cosmic Rays (UHECR). It consists of a surface array, that measures the secondary particles at ground level, and a fluorescence detector, that observes the development of EAS above the array. We report a measurement of the "hybrid" spectrum of UHECR above...

78. Large scale anisotropy studies with the Pierre Auger Observatory

Dr Raffaella Bonino (IFSI-INAF, INFN Torino)

Completed at the end of 2008, the Pierre Auger Observatory has been continuously operating for more than seven years, collecting a statistics of cosmic rays that already allows one to be sensitive to intrinsic anisotropies in their sky distributions at the 1% level at EeV energies. We present here the most recent results about the search for large scale anisotropies, reporting both the phase...

62. AERA, the Auger Engineering Radio Array

Mr Benjamin Fuchs (Karlsruhe Institut für Technologie, KIT)

The Auger Engineering Radio Array (AERA) is being deployed at the Pierre Auger Observatory in Argentina. AERA is designed as a 20 km$^{2}$ radio array with 160 autonomous radio detection stations to measure the radio emission from ultra-high energetic cosmic ray air showers above $10^{17}$ eV. AERA is based on experiences made with various prototype radio stations at the Pierre Auger...

40. The Tunka-133 EAS Cherenkov light array: status, all particle energy spectrum and future plans.

Prof. Leonid Kuzmichev (SINP MSU)

27/05/2011, 12:30

The new EAS Cherenkov light array Tunka-133 with ~1 km2 geometric area has been installed in the Tunka Valley (50 km from the Lake Baikal) in 2009. We describe the array construction, the DAQ and methods of the array calibration. The method of energy reconstruction, providing high energy resolution, and the absolute energy calibration are discussed. The all particle energy spectrum, based on...

71. Telescope Array: the latest results

Prof. Petr Tinyakov (ULB (Université Libre de Bruxelles))

27/05/2011, 12:50

The Telescope Array ultra-high energy cosmic ray detector, situated in Utah, USA, is taking data since March 2008. I will present the latest results of the spectrum, composition and anisotropy studies by the Telescope Array.
