Depth of Maximum of Air-Shower Profiles above $10^{17.8}$eV Measured with the Fluorescence Detector of the Pierre Auger Observatory and Mass Composition Implications

open access: yesInternational Conference on Rebooting Computing, 2023
After seventeen years of operation, the first phase of measurements at the Pierre Auger Observatory finished and the process of upgrading it began. In this work, we present distributions of the depth of air-shower maximum, 𝑋 max , using profiles measured

Measurement of UHECR energy spectrum with the Pierre Auger Observatory and the Telescope Array

open access: yesInternational Conference on Rebooting Computing, 2023
The measurement of the energy spectrum of ultra-high-energy cosmic rays (UHECRs) is of crucial importance to clarify their origin, acceleration mechanisms, and propagation processes in inter-Galactic and Galactic space.

Search for photons above 1019 eV with the surface detector of the Pierre Auger Observatory [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2022
We use the surface detector of the Pierre Auger Observatory to search for air showers initiated by photons with an energy above 1019 eV. Photons in the zenith angle range from 30∘ to 60∘ can be identified in the overwhelming background of showers ...

Mass Composition from 3 EeV to 100 EeV using the Depth of the Maximum of Air-Shower Profiles Estimated with Deep Learning using Surface Detector Data of the Pierre Auger Observatory

open access: yesInternational Conference on Rebooting Computing, 2023
We present a new analysis for estimating the depth of the maximum of air-shower profiles, 𝑋 max , to investigate the evolution of the ultra-high-energy cosmic ray mass composition from 3 to 100 EeV.

Highlights from the Pierre Auger Observatory [PDF]

open access: yesAIP Conference Proceedings, 2011
The Pierre Auger Observatory is being used to observe the ultra‐high energy sky with unprecedented sensitivity. In this paper we describe the status of the Observatory, and the philosophy of the collaboration which aims to take advantage of the “hybrid” nature of the detector to reduce reliance on air shower simulations.
