Search for Ultra-High Energy Photons with the Pierre Auger Observatory
Data taken at the Pierre Auger Observatory are used to search for air showers initiated by ultra-high energy (UHE) photons. Results of searches are reported from hybrid observations where events are measured with both fluorescence and array detectors. Additionally, a more stringent test of the photon fluxes predicted with energies above 10 eV is made using a larger data set measured using only ...
متن کاملSearch for clustering of ultra high energy cosmic rays from the Pierre Auger Observatory
We present the results of a search for clustering among the highest energy events detected by the surface detector of the Pierre Auger Observatory between 1 January 2004 and 31 August 2007. We analyse the autocorrelation function, in which the number of pairs with angular separation within an angle α is compared with the expectation from an isotropic distribution. Performing a scan in energy ab...
متن کاملCharacteristics of geomagnetic cascading of ultra-high energy photons at the southern and northern sites of the Pierre Auger Observatory
Cosmic-ray photons above 10 eV can convert in the geomagnetic field and initiate a preshower, i.e. a particle cascade before entering the atmosphere. We compare the preshower characteristics at the southern and northern sites of the Pierre Auger Observatory. In addition to a shift of the preshower patterns on the sky due to the different pointing of the local magnetic field vectors, the fact th...
متن کاملStudies of the ultra-high energy cosmic ray composition at the Pierre Auger Observatory
The hybrid Pierre Auger Observatory, consisting of fluorescence detector with 24 telescopes and of surface detector with more than 1600 water Cherenkov stations, has been collecting high quality data since January 2004. In this contribution we present namely current results of studies of ultra-high energy cosmic ray composition and related results concerning the energy spectrum of these particl...
متن کاملUltrahigh Energy Neutrinos at the Pierre Auger Observatory
The observation of ultrahigh energy neutrinos (UHEνs) has become a priority in experimental astroparticle physics. UHEνs can be detected with a variety of techniques. In particular, neutrinos can interact in the atmosphere (downward-going ν) or in the Earth crust (Earth-skimming ν), producing air showers that can be observed with arrays of detectors at the ground. With the Surface Detector Arra...
