RESULTS FROM THE PIERRE AUGER OBSERVATORY
The Pierre Auger Observatory has been designed to investigate the origin and the nature of Ultra High Energy Cosmic Rays using a hybrid detection technique. It is located on a plateau in the Province of Mendoza, Argentina, and consists of a surface array of about 3000 km2 overlooked by 24 air fluorescence telescopes grouped in 4 sites which together provide a powerful instrument for air shower reconstruction. The southern of the Auger Observatory has been completed in June 2008 and it is taking data smoothly since 2004. A review of selected results is presented with the emphasis given to the measurement of energy spectrum,
chemical composition and search for photon and neutrinos as primary particles

Results from the Pierre Auger Observatory
The Pierre Auger Observatory has been designed to investigate the origin and the nature of Ultra High Energy Cosmic Rays using a hybrid detection technique. It is located on a plateau in the Province of Mendoza, Argentina,
and consists of a surface array of about 3000 km^2 overlooked by 24
air fluorescence telescopes grouped in 4 sites, which together provide a
powerful instrument for air shower reconstruction.
The combination of information from the surface array, measuring the
lateral distributions of secondary particles at the ground, and the
fluorescence telescopes, observing the longitudinal profile, enhances
the reconstruction capability with respect to the individual detector components.
The Observatory was completed in 2008 and it is taking data smoothly since 2004. Moreover, detector enhancements are being constructed to extend the sensitivity of the Observatory towards the lower energies.
A review of selected results is presented with the emphasis given to the measurement of energy spectrum, arrival directions, chemical composition and search for photons and neutrinos as primary particles
Search for primary photons and neutrinos in the ultra-high energy cosmic rays with the Pierre Auger Observatory
Along with primary protons and nuclei most of the scenarios of the origin of cosmic rays predict fluxes of photons and neutrinos at the highest energies. Thanks to the huge collection area and the hybrid design, combining ground array and fluorescence detection techniques, the Pierre Auger Observatory is a unique tool to search for primary photons and neutrinos in ultra-high energy cosmic rays. Implications of these searches extend from astrophysics to fundamental and particle physics. Current results and future perspectives are reported
Results from the Pierre Auger Observatory
he Pierre Auger Observatory has been designed to investigate the origin and the nature of Ultra High Energy Cosmic Rays using a hybrid detection technique. It islocated in the Province of Mendoza, Argentina, and consists of a surface array of about 3000 km2 overlooked by 27 air fluorescence telescopes grouped in four sites, which together provide a powerful instrument for air shower reconstruction. The combination of information from the surface array, measuring the lateral distributions of secondary particles at the ground, and the fluorescence telescopes, observing the longitudinal profile, enhances the reconstruction capability with respect to the individual detector components. Ultra High Energy Cosmic Rays offer also the unique chance of investigating particle interactions over an energy range well beyond the one covered by present and future ground-based particle accelerators. A review of selected results is presented with the emphasis given to the measurement of energy spectrum, arrival directions, chemical composition and the search for photons and neutrinos as primary particles

Atmospheric aerosol characterization using the central laser facility at the Pierre Auger Observatory
The Fluorescence Detector of the Pierre Auger Observatory uses the atmosphere as a huge calorimeter that needs continuous
monitoring to ensure unbiased physics results. The Central Laser Facility (CLF), a calibrated laser source located near the centre
of the Observatory, is used to measure the light attenuation due to aerosols, highly variable even on time scales of one hour. Two
independent, fully compatible procedures based on the analysis of CLF vertical events have been developed. Five years of hourly
aerosol characterization are provide
