“…An upper limit on the diffuse flux of tau neutrinos from the search for ES events in data through 2008 April 30 (∼2 years of exposure with a full SD array) was reported in Abraham et al (2009). Here, the search is extended to data until 2010 May 31 (∼3.5 years of exposure with a full SD array), and an improved limit is obtained.…”

“…The procedure is identical to that used for the calculation of the exposure for a diffuse flux of UHEνs (Abraham et al 2009;Abreu et al 2011a;Guardincerri et al 2011), with the exception of the solid angle integration over the sky. The integration over the blind search time period takes into account the growth of the SD array during its construction phase and dead times of individual stations.…”

“…Several other sources of systematic uncertainties on the exposure have been investigated (Abraham et al 2009;Abreu et al 2011a). For the DG analysis, the major contributions in terms of deviation from a reference exposure come from the knowledge of neutrino-induced shower simulations (+9%, −33%), of the neutrino cross-section (±7%), and of the topography (±6%).…”

The surface detector array of the Pierre Auger Observatory can detect neutrinos with energy E ν between 10 17 eV and 10 20 eV from point-like sources across the sky south of +55• and north of −65 • declinations. A search has been performed for highly inclined extensive air showers produced by the interaction of neutrinos of all flavors in the atmosphere (downward-going neutrinos), and by the decay of tau leptons originating from tau neutrino interactions in Earth's crust (Earth-skimming neutrinos). No candidate neutrinos have been found in data up to 2010 May 31. This corresponds to an equivalent exposure of ∼3.5 years of a full surface detector array for the Earth-skimming channel and ∼2 years for the downward-going channel. An improved upper limit on the diffuse flux of tau neutrinos has been derived. Upper limits on the neutrino flux from point-like sources have been derived as a function of the source declination. Assuming a differential neutrino flux k PS · E −2 ν from a point-like source, 90% confidence level upper limits for k PS at the level of ≈5 × 10 −7 and 2.5 × 10 −6 GeV cm −2 s −1 have been obtained over a broad range of declinations from the searches for Earth-skimming and downward-going neutrinos, respectively.

Seit Mitte 2008 ist das Pierre‐Auger‐Observatorium in Argentinien zur Beobachtung der kosmischen Strahlung bei höchsten Energien vollständig ausgebaut. Es hat erstmals ein solide kalibriertes Energiespektrum, eine Messung der Schauereigenschaften und Primärmassen sowie eine anisotrope Verteilung der Ankunftsrichtungen der Teilchen geliefert. So gibt es statistisch signifikante Hinweise darauf, dass Teilchen mit Energien von mehr als 1019 eV mit den Positionen von aktiven Galaxien korrelieren. Dennoch bleiben Fragen offen, die mit dem zukünftigen Observatorium Auger‐Nord beantwortet werden sollen.
