Spectral Calibration of the Fluorescence Telescopes of the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +403
We present a novel method to measure precisely the relative spectral response of the fluorescence telescopes of the Pierre Auger Observatory. We used a portable light source based…
The Pierre Auger Observatory Upgrade - Preliminary Design Report
The Pierre Auger Collaboration, A. Aab, P. Abreu +462
The Pierre Auger Observatory has begun a major Upgrade of its already impressive capabilities, with an emphasis on improved mass composition determination using the surface detecto…
Origin of atmospheric aerosols at the Pierre Auger Observatory using studies of air mass trajectories in South America
Pierre Auger Collaboration, Gabriele Curci
The Pierre Auger Observatory is making significant contributions towards understanding the nature and origin of ultra-high energy cosmic rays. One of its main challenges is the mon…
Why should we keep measuring zenital dependence of muon flux? Results obtained at Campinas (SP) BR
B. Daniel, L. M. Santos, M. Nunes +2
The zenital dependence of muon flux which reaches the earth's surface is well known as proportional to cos^n(θ). Generally, for practical purposes and simplicity in calculations, n…
Using spherical wavelets to search for magnetically-induced alignment in the arrival directions of ultra-high energy cosmic rays
M. Zimbres, R. Alves Batista, E. Kemp
Due to the action of the intervening cosmic magnetic fields, ultra-high energy cosmic rays (UHECRs) can be deflected in such a way as to create clustered energy-ordered filamentary…
Antennas for the Detection of Radio Emission Pulses from Cosmic-Ray induced Air Showers at the Pierre Auger Observatory
P. Abreu, M. Aglietta, M. Ahlers +512
The Pierre Auger Observatory is exploring the potential of the radio detection technique to study extensive air showers induced by ultra-high energy cosmic rays. The Auger Engineer…
