A search for ultra-high-energy photons at the Pierre Auger Observatory exploiting air-shower universality

open access: yesInternational Conference on Rebooting Computing, 2021
The Pierre Auger Observatory is the most sensitive detector to primary photons with energies above ∼ 0 . 2 EeV. It measures extensive air showers using a hybrid technique that combines a fluorescence detector (FD) with a ground array of particle detectors

Weathering Incongruence in Mountainous Mediterranean Climates Recorded by Stream Lithium Isotope Ratios

open access: yesJournal of Geophysical Research: Earth Surface, Volume 129, Issue 3, March 2024.
Abstract Lithium isotope ratios (δ7Li) of rivers are increasingly serving as a diagnostic of the balance between chemical and physical weathering contributions to overall landscape denudation rates. Here, we show that intermediate weathering intensities and highly enriched stream δ7Li values typically associated with lowland floodplains can also ...

PHYSICS RESULTS OF THE PIERRE AUGER OBSERVATORY [PDF]

open access: yesAstrophysics at Ultra-High Energies, 2007
The Southern Pierre Auger Observatory is now nearing completion and the accumulating data sample has already allowed to extract scientific results of relevance for ultra-high energy cosmic-ray (UHECR) physics. This lecture focuses on the description and outcomes of the studies on the UHECR arrival directions (and in particular the anisotropy searches ...

The northern site of the Pierre Auger Observatory

open access: yesNew Journal of Physics, 2010
The Pierre Auger Observatory is an international facility dedicated to the full-sky study of the highest-energy cosmic rays. The southern site of the Auger Observatory was completed in June 2008. Data collected since January 2004 have yielded important information on the energy spectrum, the primary particle composition, the fluxes of photons and ...
