Search for signatures of magnetically-induced alignment in the arrival directions measured by the Pierre Auger Observatory
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +496
We present the results of an analysis of data recorded at the Pierre Auger Observatory in which we search for groups of directionally-aligned events (or `multiplets') which exhibit…
Precise determination of muon and EM shower contents from shower universality property
A. Yushkov, M. Ambrosio, C. Aramo +3
We present two new aspects of Extensive Air Shower (EAS) development universality allowing to make accurate estimation of muon and electromagnetic (EM) shower contents in two indep…
Applications of muon signal to electromagnetic signal showers universality for mass composition and hadronic interactions studies
D. D'Urso, M. Ambrosio, C. Aramo +4
We present the first results of the application of the recently found universality of behavior of muon signal to electromagnetic (EM) signal ratio with respect to the vertical dept…
